android重啟APP并殺掉之前的APP進程
Intent intent = applicationContext.getPackageManager().getLaunchIntentForPackage(application.getPackageName());
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_CLEAR_TASK);
applicationContext.startActivity(intent);
android.os.Process.killProcess(android.os.Process.myPid());
System.exit(0);
加上Intent.FLAG_ACTIVITY_CLEAR_TOP和Intent.FLAG_ACTIVITY_CLEAR_TASK這兩個flag可以避免重啟時黑屏一兩秒
