在seytem server中没有权限执行dumpsys package -p com.xx.launcher

执行dumpsys package -p com.xx.launcher 命令并把结果保存到/data/data/1.txt

public  void executeCommandAndWriteToFile(String command) throws IOException {
    Slog.i(PERFORMANCE_TAG, "executeCommand command: " + command );
    FileWriter writer = null;
    StringBuilder output = new StringBuilder();
    java.lang.Process process= null;
    BufferedReader bufferedReader = null;

    try {
        writer = new FileWriter("/data/data/1.txt");
        process = Runtime.getRuntime().exec(command);
        bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

        String line;
        while ((line = bufferedReader.readLine()) != null) {
            Slog.i(PERFORMANCE_TAG, "executeCommand command: line " + line );
            writer.write(line + System.lineSeparator());
        }
        writer.flush();
        process.waitFor();
    } catch (Exception e) {
        Slog.e(TAG, "executeCommand command: " + command + " error: " + e);

    }finally {
        try {
            if (bufferedReader != null) {
                bufferedReader.close();
            }
            if (writer != null) {
                writer.close();
            }
            if (process != null) {
                process.destroy();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }


}

executeCommand command: dumpsys package -p com.android.settings error: java.io.IOException: Cannot run program "dumpsys": error=13, Permission denied

也没有AVC报错，但还是关闭selinux，就可以执行成功
