Code transparency is an optional code signing and verification mechanism for apps published with the Android App Bundle. It uses a code transparency signing key, which is solely held by the app developer. Code transparency is independent of the signing scheme used for app bundles and APKs. The code transparency key is separate and different from the app signing key that is stored on Google’s secure infrastructure when using Play App Signing. How code transparency works The process works by including a code transparency file in the bundle after it has been built, but before it is uploaded to Play Console for distribution. The code transparency file is a JSON Web Token JWT that contains a list of DEX files and native libraries included in the bundle, and their hashes. It is then signed using the code transparency key that is held only by the developer. This code transparency file is propagated to the base APK built from the app bundle specifically to the main split of the base module. It can then be verified that All DEX and native code files present in the APKs have matching hashes in the code transparency file. The public key component of the code transparency signing key in the app matches the public key of the developer which must be provided by the developer over a separate, secure channel. Together, this information verifies that the code contained in the APKs matches what the developer had intended, and that it has not been modified. The code transparency file does not verify resources, assets, the Android Manifest, or any other files that are not DEX files or native libraries contained in the lib/ folder. Code transparency verification is used solely for the purpose of inspection by developers and end users, who want to ensure that code they're running matches the code that was originally built and signed by the app developer. Known limitations There are certain situations when code transparency cannot be used Apps that specify the sharedUserId attribute in the manifest. Such applications may share their process with other applications, which makes it difficult to make assurances about the code they're executing. Apps using anti-tamper protection or any other service that makes code changes after the code transparency file is generated will cause the code transparency verification to fail. Apps that use legacy Multidex on API levels below 21 Android and use feature modules. Code transparency will continue to work when the app is installed by Google Play on Android devices. Code transparency will be disabled on older OS versions. How to add code transparency Before you can add code transparency to your app, make sure that you have a private and public key pair that you can use for code transparency signing. This should be a unique key that is different from the app signing key that you use for Play App Signing, and it must be held securely and never shared outside of your organization. If you don't have a key, you can follow the instructions in the Sign your app guide to generate one on your machine. Code transparency uses a standard keystore file, so even though the guide is for app signing, the key generation process is the same. Using Android Gradle plugin Code transparency support requires Android Gradle plugin version or newer. To configure the key used for code transparency signing, add the following in the bundle block. Groovy // In your app module's file android { ... bundle { codeTransparency { signing { keyAlias = "ALIAS" keyPassword = "PASSWORD" storeFile = file"path/to/keystore" storePassword = "PASSWORD" } } ... } } Kotlin // In your app module's file android { ... bundle { codeTransparency { signing { keyAlias = "ALIAS" keyPassword = "PASSWORD" storeFile = file"path/to/keystore" storePassword = "PASSWORD" } } ... } } The key used must be one that you will only use for code transparency, and not the app signing key that is used by Play App Signing. Using bundletool on the command line Code transparency support requires bundletool version or newer, which you can download from GitHub. Run the following command to add code transparency to an Android App Bundle. The key used must be one that you will only use for code transparency, and not the app signing key that is used by Play App Signing. bundletool add-transparency \ -bundle=/MyApp/ \ -output=/MyApp/ \ -ks=/MyApp/ \ -ks-pass=file/MyApp/ \ -ks-key-alias=MyKeyAlias \ -key-pass=file/MyApp/ Alternatively, if you want to use your own signing tools, you can use bundletool to generate the unsigned code transparency file, sign it in a separate environment and inject the signature into the bundle Generate code transparency file bundletool add-transparency \ -mode=generate_code_transparency_file \ -bundle=/MyApp/ \ -output=/MyApp/ \ -transparency-key-certificate=/MyApp/ Add code transparency signature to the bundle bundletool add-transparency \ -mode=inject_signature \ -bundle=/MyApp/ \ -output=/MyApp/ \ -transparency-key-certificate=/MyApp/ \ -transparency-signature=/MyApp/signature Verify code transparency of an app There are different methods for verifying code against the code transparency file, depending on if you have the APKs installed on an Android device or downloaded locally to your computer. Using Bundletool to check an app bundle or APK set You can use bundletool to verify code transparency in an app bundle or an APK set. Use the check-transparency command to print the public certificate fingerprint For checking a bundle bundletool check-transparency \ -mode=bundle \ -bundle=/MyApp/ No APK present. APK signature was not checked. Code transparency signature is valid. SHA-256 fingerprint of the code transparency key certificate must be compared with the developer's public key manually 01 23 45 67 89 AB CD EF .. Code transparency verified code related file contents match the code transparency file. For checking a ZIP containing app's APK splits bundletool check-transparency \ -mode=apk \ -apk-zip=/MyApp/ APK signature is valid. SHA-256 fingerprint of the apk signing key certificate must be compared with the developer's public key manually 02 34 E5 98 CD A7 B2 12 .. Code transparency signature is valid. SHA-256 fingerprint of the code transparency key certificate must be compared with the developer's public key manually 01 23 45 67 89 AB CD EF .. Code transparency verified code related file contents match the code transparency file. You can optionally specify the public certificate that you want to verify the bundle or APK set against, so that you don't have to compare the hashes manually bundletool check-transparency \ -mode=bundle \ -bundle=/MyApp/ \ -transparency-key-certificate=/MyApp/ No APK present. APK signature was not checked. Code transparency signature verified for the provided code transparency key certificate. Code transparency verified code related file contents match the code transparency file. bundletool check-transparency \ -mode=apk \ -apk-zip=/MyApp/ \ -apk-signing-key-certificate=/MyApp/ \ -transparency-key-certificate=/MyApp/ APK signature verified for the provided apk signing key certificate. Code transparency signature verified for the provided code transparency key certificate. Code transparency verified code related file contents match the code transparency file. Using Bundletool to check an app installed on a device For checking an app that has been installed on an Android device, make sure the device is connected to your computer via ADB and issue to following command bundletool check-transparency \ -mode=connected_device \ -package-name=" APK signature is valid. SHA-256 fingerprint of the apk signing key certificate must be compared with the developer's public key manually 02 34 E5 98 CD A7 B2 12 .. Code transparency signature is valid. SHA-256 fingerprint of the code transparency key certificate must be compared with the developer's public key manually 01 23 45 67 89 AB CD EF .. Code transparency verified code related file contents match the code transparency file. The connected device transparency check can also optionally verify the signature against a public key that you specify bundletool check-transparency \ -mode=connected-device \ -package-name=" \ -apk-signing-key-certificate=/MyApp/ \ -transparency-key-certificate=/MyApp/ APK signature verified for the provided apk signing key certificate. Code transparency signature verified for the provided code transparency key certificate. Code transparency verified code related file contents match the code transparency file.

Thered, green and blue use 8 bits each, which have integer values from 0 to 255. This makes 256*256*256=16777216 possible colors. RGB ≡ Red, Green, Blue. Each pixel in the LED monitor displays colors this way, by combination of red, green and blue LEDs (light emitting diodes). When the red pixel is set to 0, the LED is turned off.

Penggunaan warna dengan gaya transparan dapat mempercantik tampilan aplikasi mobile kita. Android menyediakan kemudahan tersebut dengan menkonversi setiap persentase besarnya transparansi warna ke dalam HEX Number. Berikut contoh penggunaan kode warna transparan pada android Contoh untuk warna black- 000000 Jika ingin menjadikannya transparan, gunakan kode 99 untuk tranparansi sebesar 60% - 99000000 Dan berikut kode-kode yang bisa digunakan dengan ketentuan presentase tertentu. 100% — FF 95% — F2 90% — E6 85% — D9 80% — CC 75% — BF 70% — B3 65% — A6 60% — 99 55% — 8C 50% — 80 45% — 73 40% — 66 35% — 59 30% — 4D 25% — 40 20% — 33 15% — 26 10% — 1A 5% — 0D 0% — 00 Referensi Understading colors in Android! 6 chars 3Warna Netral Relatif Lebih Aman. Jika Anda masih bingung dan kesulitan dalam menentukan warna brand, salah satu opsi yang bisa digunakan adalah warna netral. Jenis warna netral yang kerap digunakan yakni abuabu, perak, emas, hitam, putih, cokelat, atau krem.

Sebuah aplikasi mobile sangat mengutamakan penampilannya. Tampilan yang menarik akan menjadikan aplikasi tersebut menarik untuk digunakan dan membuat user tidak bosan dalam menggunakannya. Baik dari sisi desain tampilan maupun perpaduan warna yang digunakan aplikasi tersebut, menjadikannya cantik dan menarik untuk digunakan. Salah satu faktor pendukung menariknya tampilan tersebut adalah warna. Android menggunakan Hex triplet sebagai attribut untuk menampilkan pilihan warna yang kita gunakan. Hex triplet adalah adalah 3 bilangan Hexadesimal, contohnya F0F8FF, yang terdiri dari 3 bilangan yaitu F0, F8 dan FF. Namun, untuk menggunakan Hex triplet sebagai referensi warna tampilan android, kita membutuhkan aplikasi tambahan yang dapat menconvert warna yang kita pilih menjadi Hex Triplet. Oleh karena itu, kita membutuhkan label warna kita sendiri untuk memudahkan kita dalam menentukan warna yang kita gunakan. Warna yang ingin kita tambahkan dapat ditambakan pada file pada sub folder “value”, dan silahkan tambakan jenis warna yang akan digunakan. Berikut label-label warna yang telah dibagikan pada forum-forum diskusi dan dapat digunakan untuk membangun aplikasi Anda FFFFFF FFFFF0 FFFFE0 FFFF00 FFFAFA FFFAF0 FFFACD FFF8DC FFF5EE FFF0F5 FFEFD5 FFEBCD FFE4E1 FFE4C4 FFE4B5 FFDEAD FFDAB9 FFD700 FFC0CB FFB6C1 FFA500 FFA07A FF8C00 FF7F50 FF69B4 FF6347 FF4500 FF1493 FF00FF FF00FF FF0000 FDF5E6 FAFAD2 FAF0E6 FAEBD7 FA8072 F8F8FF F5FFFA F5F5F5 F5F5DC F5DEB3 F4A460 F0FFFF F0FFF0 F0F8FF F0E68C F08080 EEE8AA EE82EE E9967A E6E6FA E0FFFF DEB887 DDA0DD DCDCDC DC143C DB7093 DAA520 DA70D6 D8BFD8 D3D3D3 D2B48C D2691E CD853F CD5C5C C71585 C0C0C0 BDB76B BC8F8F BA55D3 B8860B B22222 B0E0E6 B0C4DE AFEEEE ADFF2F ADD8E6 A9A9A9 A52A2A A0522D 9ACD32 9932CC 98FB98 9400D3 9370DB 90EE90 8FBC8F 8B4513 8B008B 8B0000 8A2BE2 87CEFA 87CEEB 808080 808000 800080 800000 7FFFD4 7FFF00 7CFC00 7B68EE 778899 708090 6B8E23 6A5ACD 696969 66CDAA 6495ED 5F9EA0 556B2F 4B0082 48D1CC 483D8B 4682B4 4169E1 40E0D0 3CB371 32CD32 2F4F4F 2E8B57 228B22 20B2AA 1E90FF 191970 00FFFF 00FFFF 00FF7F 00FF00 00FA9A 00CED1 00BFFF 008B8B 008080 008000 006400 0000FF 0000CD 00008B 000080 000000 003855 73000000 b3000000 00000000

Tips Android Studio 1 Inilah Hex Color Code Untuk Transparansi Bingung ingin mengtransparansikan color code di Android Studio? Nih gue ada sedikit tips untuk hal itu. Caranya gampang banget, tinggal tambahi 2 kode hexa ini di depan kode warna tersebut, sebagai contoh lu ingin menggunakan kode warna hitam dengan kode “000000”. Maka, tambahkan kode berdasarkan tingkat transparansi tersebut di depan 000000 tersebut. Berikut adalah nilai hexa berdasarkan persentasenya, cekiidoott 100% — FF 95% — F2 90% — E6 85% — D9 80% — CC 75% — BF 70% — B3 65% — A6 60% — 99 55% — 8C 50% — 80 45% — 73 40% — 66 35% — 59 30% — 4D 25% — 40 20% — 33 15% — 26 10% — 1A 5% — 0D 0% — 00 Contoh penggunaannya Gue lanjutin nih mengenai contoh penggunaannya, misalkan gue ingin menggunakan tingkat transparansinya itu 30%, berarti kode hexanya itu kan 4D ya, dan kode warna yang kita gunakan itu adalah “000000”. Nah, tinggal diubah aja nih jadi begini “4D000000”, that’s it. Sangat mudah bukan? Untuk tutorial ini sepertinya sudah cukup ya terkait transparansi warna. Semoga konten ini bisa memberikan wawasan baru dan manfaat lainnya yang bisa di dapat dari thread ini. Terima kasih dan Wassalamualaikum War’rahmatulahi Wabarakatu.

Bahanbahan: - kompi / lepi - - apkmulti tool download disini langkah-langkah: 1. copy file systemUI.apk ke folder place-apk-here-for-modding di dalam folder apkmulti tool kalian I would like some clarification on what the code in front of the HTML color code is called and how it functions. 1 I'm assuming, in the example below, the endColor of 00000000 with the two preceding 00 tells the color to be generated more transparent than say FF. 2 But what's the scale? 3 Is there some kind of hex scale that equates to certain percentages? I'm really confused and can find no documentation because I'm not even sure of the the terminology I should be searching for other than 'xml transparent gradient' which doesn't tell me what I want to know. Any/All help is appreciated. Thanks

PilihIsi Untuk Mengganti Latar Dengan Warna Solid. Aplikasi ini tersedia di playsotre dan apps. Color / transparan di xml anda jika anda harus memaksanya karena beberapa alasan (jelas warna ini tidak diwarisi oleh pandangan anak) Jika anda ingin transparansi, masukkan saja 80 sebelum kode hash yang sebenarnya:

Tutorial kali ini, saya akan membahas tentang teknik membuat background untuk android. Teknik berikut ini semuanya menggunakan XML di folder res, tidak ada kode java sama sekali. Ada 4 teknik yang akan saya bahas yaitu Teknik background warna Teknik Gradient Teknik Wallpaper/Gambar Teknik pattern repeat/pola Teknik Background Warna Teknik ini adalah teknik yang paling mudah, kita cukup buka file xmlnya dan tambahkan paramater androidbackground”kodewarna” di Layout. androidbackground="A4C639" Background warna Teknik Gradient Teknik ini adalah variasi dari teknik pertama, dengan gradient, kita bisa membuat background activity dengan lebih dari satu warna, Facebook App di Faceook menggunakan teknik ini untuk halaman loginnya dengan mode gradient radial. Sekedar tambahan, mode gradient ini ada dua yaitu Radial dan linier. Untuk teknik kedua ini, kita harus buat file dulu dengan nama di folder drawable Selanjutnya tambahkan baris berikut ke layout yang akan memakai gradient tersebut androidbackground="drawable/gradient" Background gradient jika anda kesulitan membuat gradient sendiri, silahkan masuk ke Diwebsite ini ada tool untuk menggenerate gradient dengan mudah. Teknik Wallpaper Teknik ini paling sering dipakai karena cukup mempunyai satu gambar di drawable, lalu tinggal tambahkan baris androidbackground="drawable/namagambar" Background Gambar Teknik Pattern Teknik ini adalah variasi dari teknik Wallpaper, teknik ini dipakai untuk pola yang berulang seperti ukiran, batik,kotak kotak, dan pola pola lainnya. Untuk pattern, anda bisa mengambilnya secara gratis di Teknik ini hampir sama dengan gradient. Silahkan sediakan dulu background patternya, pattern ini biasanya ukurannya kecil dan nanti akan di repeat Teknik ini mirip dengan membuat background pattern berbasis CSS di webdesain. Anggaplah anda punya file , maka buatlah file baru di drawable dengan nama Setelah itu pakai di layout androidbackground="drawable/pattern" Background pattern Download code sample Saya yakin sebagian dari anda bingun kalau cuma di beri potongan kode, karena itulah saya sediakan proyek eclipsenya agar anda tinggal download dan mencobanya sendiri .Silahkan download source codenya disini.
