aarch64-linux-android-strip file Missing

I had the same problem when using NDK version 17.0.4754217 (maybe on newer versions, it doesn't happen). You can workaround this issue by adding the following code in your gradle.build:

packagingOptions{
    doNotStrip '*/mips/*.so'
}

Or

packagingOptions{
    doNotStrip '*/mips/*.so'
    doNotStrip '*/mips64/*.so'
}

If you are using native code (C++), I recommend add the following code too:

ndk {
    abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86' // <- only the supported ones
}

To make sure you won't embed any MIPS binary.

Add these to gradle.build file:

packagingOptions{
    doNotStrip '*/mips/*.so'
    doNotStrip '*/mips64/*.so'
}

I have Android Studio 3.1.2 and after I approved the IDE suggested updates I got the next errors:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task '...'.

Caused by: org.gradle.process.internal.ExecException: A problem occurred starting process 'command '/Users/.../Library/Android/sdk/ndk-bundle/toolchains/mips64el-linux-android-4.9/prebuilt/darwin-x86_64/bin/mips64el-linux-android-strip'

Caused by: java.io.IOException: error=2, No such file or directory

It looks like there is a problem with NDK version 17.0.4754217.

Since I don't use ndk components in my project for me the solution was removing NDK from the SDK Manager.

Go to SDK Manager -> SDK Tools tab -> uncheck NDK -> Apply.
