Android - 在 4.2.2 (Nexus 10) 上显示/隐藏系统栏

Question

我遇到了 Nexus 10 - 4.2.2 的问题。我在 Galaxy Tab 10.1 和 4.0.4 上测试了下面的代码，它运行良好:

try 
{
    Process proc = Runtime.getRuntime().exec(new String[]{"sh","startservice","-n","com.android.systemui/.SystemUIService"});
    proc.waitFor();
} 
catch (Exception e) 
{
    e.printStackTrace();
}

try
{
    //REQUIRES ROOT
    Process proc = Runtime.getRuntime().exec(new String[]{"su","-c","service call activity 42 s16 com.android.systemui"}); //WAS 79
    proc.waitFor();
}
catch(Exception ex)
{
    //Toast.makeText(getApplicationContext(), ex.getMessage(), Toast.LENGTH_LONG).show();
}

但在 Nexus 10 系统栏之后不会显示，只是隐藏。

在4.2.2及其他系统显示和隐藏系统栏和通知栏:

隐藏:

    try
    {
        String command;
        command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib service call activity 42 s16 com.android.systemui";
        Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);
        proc.waitFor();
    }
    catch(Exception ex)
    {
        Toast.makeText(getApplicationContext(), ex.getMessage(), Toast.LENGTH_LONG).show();
    }

显示:

    try 
    {
         String command;
         command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib am startservice -n com.android.systemui/.SystemUIService";
         Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);
         proc.waitFor();
    } 
    catch (Exception e) 
    {
          e.printStackTrace();
    }
