How do you run adb from Android?

[sharpordie]

I used the asset files from your project:
https://github.com/nightmare-space/adb_tool/tree/main/assets/android

And I used this code to extract them to the phone's memory and make them executable with chmod +x. Unfortunately I always get a permission error when I try running adb --version command.

List<String> androidFiles = [
    'adb',
    'adb_binary',
    'adb.bin-armeabi',
    'libbrotlidec.so',
    'libbrotlienc.so',
    'libc++_shared.so',
    'liblz4.so.1',
    'libprotobuf.so',
    'libusb-1.0.so',
    'libz.so.1',
    'libzstd.so.1',
    'libbrotlicommon.so',
];

for (var element in androidFiles) {
    ByteData data = await rootBundle.load('assets/android/$element');
    List<int> bytes = data.buffer.asUint8List(data.offsetInBytes, data.lengthInBytes);
    var program = '/data/data/com.example.my_app/files/usr/bin/$element';  // Is it correct?
    var file = File(program);
    file = await file.create(recursive: true);
    file.writeAsBytes(bytes);
    await Process.run('chmod', ['+x', program]);
}

var results = await Process.run('/data/data/com.example.my_app/files/usr/bin/adb', ['--version']);
var version = results.stdout;

My application name is com.example.my_app. Did I put the asset files in the right place?

Thank you in advance.

And what is the purpose of the native adblib library here so: https://github.com/nightmare-space/adb_tool/tree/main/android/app/src/main/java/com/nightmare/adbtools/adblib

It seems to be an implementarion of adb but in java... Are you really using the adb binary from assets in adb_tool?

what the result of results.stdout,now i haven't see any problem with your code,have you try downgrade target version to 28?

adblib is the java code which implement adb protcol,but it only work with otg,the other time this project allways use adb binary from assets.

I replaced targetSdkVersion flutter.targetSdkVersion with targetSdkVersion 28 and everything works!

Thanks you very much!
