My android app was crashing when i build a signed apk. The crash was not seen when i did a debug build. The build.gradle file is like this:
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.config
}
debug {
debuggable true
}
}
setting minifyEnabled to false is not the correct solution, that would disable proguard while building the release version
The reason why setting minifyEnabled is working is because proguard might be obfuscating jsoup.
So, you should keep minifyEnabled as true and include these rules for jsoup in your proguard-rules.txt file to prevent the app from crashing :
-keep public class org.jsoup.** {
public *;
}
What i did to prevent the app from crashing is that i have made minifyEnabled to false from true in the build.gradle file. In that file i have made the following change.
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.config
}
debug {
debuggable true
}
}
If anybody have any other answers please post it here.

I have created the .aar(Android library) for ionic 6/cordova project. But unable to obfuscate the java class files, i.e, able to see the content of the file. Below is the configuration used in app level build.gradle.
buildTypes {
release {
signingConfig signingConfigs.release
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
debuggable false
}
debug {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
It would be great if some one help on this?
I want to obfuscate my android code, I have set minifienable true and setup proguard file, but after generating apk and decompile, the code is not obfuscated. This is my proguard :
my proguard file:
-dontwarn com.huawei.**
-dontwarn org.conscrypt.*
-dontwarn org.openjsse.javax.net.ssl.*
-dontwarn org.openjsse.net.ssl.OpenJSSE
my build.gradle file
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
debug{
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
To enable ProGuard in Android Studio. Below is the sample how to enable default ProGuard in Android Studio.
Go to the build.gradle file of app
enable the proguard minifyEnabled true and useProguard true
enable shrinkResources true to reduce the APK size by shrinking resources.
proguardFiles getDefaultProguardFile('proguard-android.txt') to enable the default one. If you want to use your own proguard file then use the below rules.
release
{
debuggable false
useProguard true
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
delete build file
invalidate cache and restart android studio
I got this warning message:
This App Bundle contains Java/Kotlin code, which might be obfuscated. We recommend you upload a deobfuscation file to make your crashes and ANRs easier to analyze and debug
what does it mean? what is the shortest solution for this?
Seems like it's a warning message coming from the new play console, you can solve it just by setting your minimum api level to 29 or even better by uploading the retrace mapping file as described here.
Enable minify :
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
After building apk/app bundle you can find /app/build/outputs/mapping/release/mapping.txt file . New console will allow you to upload mapping.txt along with your apk or bundle. You can find this option from App bundles and APKs menus.(According to this)
Just changing minifyEnabled to true worked for me
You can solve this by just enabling minify in your build. gradle(app) file:
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
Just enable minify in your build.gradle(app) file:
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
proguard-android-optimize.txt sometimes is unsupported so using the following is safer (see this):
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
When i try to do minify enabled true in my build.gradle file using below code application is crashed :
Code
buildTypes {
release {
debuggable false
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
debug{
debuggable true
minifyEnabled true
shrinkResources false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
when I did: minifyEnabled true after building release apk: app-release.apk, the app crashed.
when I did: minifyEnabled false after building release apk: app-release.apk, the build is okay.
enter image description here
As indicated ref resource, minifyEnabled will remove unused codes. In your situation, there might be methods which is used with JNI or else and compiler did not known it's used. Again according to ref, you can specify which files to keep from examination of built-in minify (same as proguard).
The answer is here
As given in the error message the classloader was not able to find the class org.apache.xerces.datatype.DatatypeFactoryImpl
Proguard is changing the class name to stop this from happening you can add
-keep class org.apache.**{ *; }
in your progurad-rules.pro file
Add this to proguard
-keep public class jp.co.soramitsu.iroha.android.** {
public protected *;
public private *;
}
I tried to proguard my app. It successfully obfuscated the apk. However, when i try to view the java code of my apk using Apk_oneclick, I am able to. I have created a release version of my apk. Still the problem persist. Any help would be much appreciated.
Thanks in advance.
build.gradle:
Proguard Rules:
Java code from the release-apk:
For enabling ProGuard configurations for your application you need to enable it in your module level gradle file. you need to set the value of minifyEnabled true.
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
You can also enable shrinkResources true which will remove resources that ProGuard flaggs as unused.
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
You need to set following property
and add some rules in proguard-android
buildTypes {
release {
debuggable false
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
Got it working. Cleaned the project and ran the same with some changes in the Proguard rules.
