The first time a debug build is done on any given machine, the Android Gradle plugin creates the debug.keystore file with a randomly-generated key, and then uses it for all subsequent debug builds of all apps on that machine. Unfortunately it looks like there's been a backward-incompatible change to the file's format, so files created by new Java versions (e.g. the version that comes with new versions of Android Studio) cannot be read by the Java version that Briefcase currently uses.

Based on this discussion, we could fix this by moving to Java 8u301 or newer. I've confirmed that it works OK with Corretto version 1.8.0_352.

Such a new version is not available at https://github.com/AdoptOpenJDK/openjdk8-binaries, which Briefcase currently uses. But its successor, https://adoptium.net/, currently offers version 8u362. See #1065.

This is probably not a new problem, because Android Studio has come with Java 11 since 2021. We just haven't seen it before because most of our users are Android novices whose first Android build was through Briefcase, not Android Studio.

i using command briefcase package android
but get error like this

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':app:packageDebug'.

A failure occurred while executing com.android.build.gradle.tasks.PackageAndroidArtifact$IncrementalSplitterRunnable
com.android.ide.common.signing.KeytoolException: Failed to read key AndroidDebugKey from store "/root/.android/debug.keystore": Invalid keystore format

how solution

and how to use own sdk root i get message like this

The location pointed to by the ANDROID_SDK_ROOT environment

how to use own sdk root

my .bashrc file is

for examples

#export JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64/
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/

You can work around the "Invalid keystore format" error by deleting the debug.keystore file and then running briefcase again.

The "doesn't appear to contain an Android SDK" error means that either the ANDROID_SDK_ROOT directory doesn't exist, or it doesn't contain an executable cmdline-tools/latest/bin/sdkmanager.

is it possible to build an Android briefcase with our own keystore like the myown.keystore file

Briefcase doesn't currently have an option for this (#865 (comment)). You can do it by using Android Studio to open the build/.../android/gradle directory, and then running the command Build > Generate Signed Bundle / APK.

Instead of installing the APK manually, try using briefcase run android, then you should see the error messages.

FYI - I've opened #1268 so the feature request of signing Android apps isn't forgotten.
