Android流氓代码块(亲测可行）

开机自启动（小米需要在安全中心设置自启动）

//在广播中声明  String action = intent.getAction();      if (action.equals("android.intent.action.BOOT_COMPLETED")) {            Intent activity = new Intent(context, SecondActivity.class);            activity.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);            context.startActivity(activity);     }   <receiver android:name=".xxx.xxx">            <intent-filter>                <action android:name="android.intent.action.BOOT_COMPLETED"/>            </intent-filter>  </receiver>  //权限<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

静默安装（需要root）

    public static boolean installUseRoot(String filePath) {        if (TextUtils.isEmpty(filePath))            throw new IllegalArgumentException("Please check apk file path!");        boolean result = false;        Process process = null;        OutputStream outputStream = null;        BufferedReader errorStream = null;        try {            process = Runtime.getRuntime().exec("su");            outputStream = process.getOutputStream();            String command = "pm install -r " + filePath + "\n";            outputStream.write(command.getBytes());            outputStream.flush();            outputStream.write("exit\n".getBytes());            outputStream.flush();            process.waitFor();            errorStream = new BufferedReader(new InputStreamReader(process.getErrorStream()));            StringBuilder msg = new StringBuilder();            String line;            while ((line = errorStream.readLine()) != null) {                msg.append(line);            }            Log.d(TAG, "install msg is " + msg);            if (!msg.toString().contains("Failure")) {                result = true;            }        } catch (Exception e) {            Log.e(TAG, e.getMessage(), e);        } finally {            try {                if (outputStream != null) {                    outputStream.close();                }                if (errorStream != null) {                    errorStream.close();                }            } catch (IOException e) {                outputStream = null;                errorStream = null;                process.destroy();            }        }        return result;    }

关机代码块（root）

    public static void closeOs(Context context) {        try {            Process proc = Runtime.getRuntime().exec(new String[]{"su", "-c", "reboot -p"});  //关机        } catch (IOException e) {            e.printStackTrace();        }    }
