android 重启应用进程

//多种方式重启应用进程public class MainActivity
{//重启当前Applicationprivate void restartApplication(){final Intent intent = getPackageManager().getLaunchIntentForPackage(getPackageName());intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);startActivity(intent);}// 使用 AlarmManager 来帮助重启public static void restartByAlarm(Context context, Class<?> cls){Intent mStartActivity = new Intent(context, cls);int mPendingIntentId = 123456;PendingIntent pIntent = PendingIntent.getActivity(context, mPendingIntentId, mStartActivity, PendingIntent.FLAG_CANCEL_CURRENT);AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);alarmManager.set(AlarmManager.RTC, System.currentTimeMillis() + 500, pIntent);System.exit(0);}//使用 killProcesspublic static void restartByKillProcess(Context context, Class<?> cls){Intent intent = new Intent(context, cls);intent.addFlags(FLAG_ACTIVITY_NEW_TASK);context.startActivity(intent);android.os.Process.killProcess(android.os.Process.myPid());}//通过清栈触发应用重启。但不会重启 application ，与应用相关的静态变量也会更重启前一样。public static void restartByClearTop(Context context){Intent intent = context.getPackageManager().getLaunchIntentForPackage(context.getPackageName());intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);context.startActivity(intent);}//利用系统重启api触发应用重启public static void restartBySystemApi(Context context){ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);manager.restartPackage(context.getPackageName());}//通过 Intent.makeRestartActivityTask 来触发应用重启，跟 restartByClearTop 类似。但不会重启 application ，与应用相关的静态变量也会更重启前一样。public static void restartByCompatApi(Context context, Class<?> cls){Intent intent = new Intent(context, cls);Intent restartIntent = Intent.makeRestartActivityTask(intent.getComponent());context.startActivity(restartIntent);System.exit(0);}/*** 5.1 版本以后可以借助 JobScheduler 来重启应用** @param context*/public static void restartByJobScheduler(Context context, Class<?> cls){if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){int delayTimeMin = 1000;int delayTimeMax = 2000;MyJobSchedulerService.setMainIntent(new Intent(context, cls));JobInfo.Builder jobInfoBuild = new JobInfo.Builder(0, new ComponentName(context, MyJobSchedulerService.class));jobInfoBuild.setMinimumLatency(delayTimeMin);jobInfoBuild.setOverrideDeadline(delayTimeMax);JobScheduler jobScheduler = (JobScheduler) context.getSystemService(JOB_SCHEDULER_SERVICE);jobScheduler.schedule(jobInfoBuild.build());System.exit(0);}}@TargetApi(Build.VERSION_CODES.LOLLIPOP)static class MyJobSchedulerService extends JobService{private static Intent mIntent;public static void setMainIntent(Intent intent){mIntent = intent;}@Overridepublic boolean onStartJob(JobParameters params){startActivity(mIntent);jobFinished(params, false);return false;}@Overridepublic boolean onStopJob(JobParameters params){return false;}}}

重启运行App的当前设备

Process process = Runtime.getRuntime().exec("reboot");process.waitfor();
