Android studio- adding signing configurations to gradle
android, android-install-apk, android-studio, code-signing
Solution
There is a mistake in the `buildTypes.release` block. The signing config should be:
signingConfig signingConfigs.release
Note, that this is how you named the configuration in the `signingConfigs` block above.
Also leave out the signing config in the `buildTypes.debug` block (or, if you really want to have it, set it like above).
Problem
I am very new to the android world and I was trying to just get to run a simple hello world app on my phone. when I tried this I learnt that the APK generated by an android studio is an unsigned one. So to sign this I have gone through the process of creating a Key store and then a private Key, its alias and I was successful in signing the APK and installing on my phone and running it too. Then I went through this link for adding signing configurations to the gradle to automatically sign the release with the newly created key store file. I have followed the steps n the above link properly and did not miss anything but still when I finish my signing configurations I have an error saying Gradle project sync failed.Basic functionality(eg. editing, debugging) will not work properly. Error:(19, 0) Could not find property 'config' on SigningConfig container. I was taken by a surprise! and now I am not able to sign my APKs manually too. Now when I try to sign manually, it says the gradle is not in sync I guess this file will be of help to help me solve this error. build.gradle of the project. I am trying to understand is what is mentioned here is same as the one I configured through the Android Studio UI while making the signing configurations. ``` apply plugin: 'com.android.application' android { signingConfigs { release { storeFile file("<path>\\firstKeystore.jks") storePassword "******" keyAlias "usual password" keyPassword "******" } } compileSdkVersion 19 buildToolsVersion '20.0.0' defaultConfig { applicationId 'com.tech.vasanth.newsfeed' minSdkVersion 19 targetSdkVersion 19 versionCode 1 versionName '1.0' } buildTypes { release { runProguard false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' signingConfig signingConfigs.config debuggable false jniDebugBuild false renderscriptDebugBuild false zipAlign true } debug { signingConfig signingConfigs.config } } productFlavors { } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) } ```
