run-as Package'abc'未知 - Galaxy S4 Jellybean或Android 4.3

Question

我无法为运行Jellybean 4.2.2的Galaxy S4运行run-as(或ndk-gdb).

~  $ adb shell
shell@android:/ $ run-as a.b.c ls
run-as: Package 'a.b.c' is unknown

对于pre-ICS设备,这个问题有多个答案,但这些答案似乎已在ICS中得到修复.

更新 - 2013年8月:在最初出现在带有Jellybean 4.2.2的Galaxy S4之后,现在似乎是所有4.3设备上的运行问题.看到这个Android bug.

请在此处查看已确认的Android问题.

更新 - 2013年11月:谷歌发布了修复Android 4.4中运行的修补程序.

Answer 1

通过将此添加到活动中找到成功:

private void startGdbServer() {   
    try {
        new ProcessBuilder()
        .command(getFilesDir().getParent() + "/lib/gdbserver", "tcp:5039", "--attach" ,"" + android.os.Process.myPid())
        .redirectErrorStream(true)
        .start();
    } catch (IOException e) {
        Log.e(TAG, "IOException failed to start gdbserver");
    }
}

然后我将startGdbServer包装在Android服务中并更新ndk-gdb脚本以启动服务器而不是run-as命令.

这是明显的补充:

<service android:enabled="true" android:name="com.apportable.activity.GdbServerService"
    android:label="@string/app_name" android:icon="@drawable/icon">
    <intent-filter >
        <action android:name="apportable.FoundationTests.GdbServerService" />
    </intent-filter>
</service>

以下是相关的ndk-gdb更改(在python中):

    remote_gdbserver = '/data/data/' + env['APPLICATION_IDENTIFIER'] + '/lib/gdbserver'

    print "Attaching to pid " + pid
    # Android 4.2 requires the --user 0 option. Earlier versions cannot have it

    results = env.Execute([env['ADB'], 'shell', 'am'])
    if "--user" in results:
        user_option = "--user 0"
    else:
        user_option = ""

    adb.AsyncShell(env, 'am startservice ' + user_option + ' -a ' + env['APPLICATION_IDENTIFIER'] + '.GdbServerService --es gdbserver_name ' + remote_gdbserver + ' --ei gdbserver_port ' + str(env['ANDROID_REMOTE_DEBUG_PORT']))

    # HACK: magic number. ensure the gdb server is actually up and running
    time.sleep(2)  # 1 is usually enough, but not always, like after reboot or with heavy system load

    adb.Forward(env, env['ANDROID_LOCAL_DEBUG_PORT'], env['ANDROID_REMOTE_DEBUG_PORT'])

    adb.Pull(env, process_path, '/system/bin/app_process')

    setup_path = '"' + setup_path + '"'

    if env['CGDB'] is not None:
        cmd = [env['CGDB'], '-d', env['GDB'], '--', '-x', setup_path]
    else:
        cmd = [env['GDB'], '-x', setup_path]

    env.RunCommand(cmd)
