Uploading debug symbols to Google Play Store

Posted by | Android, QT |

Did a quick google search and found this

I have the following components installed:

  • NDK (Side by side)
  • CMake
  • Android SDK Command-line Tools (latest)

Experimentation

Tried gradle version 7.0.3:

buildscript {
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.0.3'
    }
}

but got:

FAILURE: Build failed with an exception.

* Where:
Build file 'E:\repos\build\lgA\android-build\build.gradle' line: 17

* What went wrong:
A problem occurred evaluating root project 'android-build'.
> Failed to apply plugin 'com.android.internal.application'.
   > Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8.
     You can try some of the following options:
       - changing the IDE settings.
       - changing the JAVA_HOME environment variable.
       - changing `org.gradle.java.home` in `gradle.properties`.

so I left 4.1.3 and tried to add both, see the docs

android.defaultConfig.ndk.debugSymbolLevel = 'FULL'

and

android.buildTypes.release.ndk.debugSymbolLevel = 'FULL'

to gradle.properties, but *.debug files were not added to aab file.

As an experiment tried not to separate debug information:

Tried to build QT with Java 11:

Note: JDK 11 or earlier must be used to properly build Qt for Android.

and switched to Gradle 7.0.3, but it did not help.

When I upload my app I get a warning:

This APK contains native code, and you’ve not uploaded debug symbols. We recommend you upload a symbol file to make your crashes and ANRs easier to analyze and debug. Learn More

Finally I added

android {
    ...
    defaultConfig {
        resConfig "en"
        minSdkVersion qtMinSdkVersion
        targetSdkVersion qtTargetSdkVersion
        ndk.abiFilters = qtTargetAbiList.split(",")
        ndk.debugSymbolLevel "FULL"
    }
}

and Gradle started to generate android-build\build\outputs\native-debug-symbols\release\native-debug-symbols.zip file of 241 MB size.

Other warnings:

This APK results in unused code and resources being sent to users. Your app could be smaller if you used the Android App Bundle. By not optimizing your app for device configurations, your app is larger to download and install on users’ devices than it needs to be. Larger apps see lower install success rates and take up storage on users’ devices.

There is no deobfuscation file associated with this APK. If you use obfuscated code (R8/proguard), uploading a deobfuscation file will make crashes and ANRs easier to analyze and debug. Using R8/proguard can help reduce app size. Learn More
