A little background. I have been building/debugging/testing my simple App for a few months with no problems. Build/install on AVD or my actual S9 phone. All worked just fine for months. Now, ready for my first beta release to the Play Store (my first app ever). So, I followed instructions on 'signing' my app. That worked and I uploaded my app bundle to the Play Store. Now I can't build/debug/install at all in Android Studio anymore.
Error: The apk for your currently selected variant (app-release-unsigned.apk) is not signed. Please specify a signing configuration for this variant (release).
Debug (Shift+F9) produces the above error and shows the "Edit configuration" dialog.
I click on the "Fix" button and from there I have no idea what to do. Or how to use these different build configurations.
build.gradle
apply plugin: 'com.android.application'
android {
signingConfigs {
debug {
storeFile file(var)
storePassword 'xxx'
keyAlias = 'xxx'
keyPassword 'xxx'
}
}
compileSdkVersion 29
buildToolsVersion "29.0.1"
defaultConfig {
applicationId "com.birdersdiary.mobile"
minSdkVersion 15
targetSdkVersion 29
versionCode 1
versionName "b1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.0.0'
implementation 'androidx.preference:preference:1.1.0'
implementation 'androidx.lifecycle:lifecycle-extensions:2.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}
Once I click on the "FIX" button I am taken to the "Run/Debug Configurations" dialog. And from there it is completely oblivious to me what needs to happen in order to Fix the problem.
Any assistance greatly appreciated.
You can solve this problem by doing any of the following
You need to switch your build variant back to debug you can do this by holding Ctrl+Alt+A on windows or CMD+ALT+A on mac then typing variant
in the search bar, select build variant
, this would show the build variant option in the left side of your android studio screen then you should select the variant that has debug appended to the name.
If you want to use a release version you need to instruct android studio how to find the keys to sign the apk
Add this to your app-level build.gradle
file
apply plugin: 'com.android.application'
android {
signingConfigs {
debug {
storeFile file(var)
storePassword 'xxx'
keyAlias = 'xxx'
keyPassword 'xxx'
}
release {
storeFile file(var)
storePassword 'xxx'
keyAlias = 'xxx'
keyPassword 'xxx'
}
}
compileSdkVersion 29
buildToolsVersion "29.0.1"
defaultConfig {
applicationId "com.birdersdiary.mobile"
minSdkVersion 15
targetSdkVersion 29
versionCode 1
versionName "b1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.0.0'
implementation 'androidx.preference:preference:1.1.0'
implementation 'androidx.lifecycle:lifecycle-extensions:2.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}
replace the placeholders with the actual value.
