android 后台被数据清理后切换到前台数据丢失问题

1.简单粗暴的方式就是检测上到数据丢失了给用户重启，如果页面太多的情况保存数据势必不可行

/* 容易被销毁时候被调用

* @see android.app.Activity#onSaveInstanceState(android.os.Bundle)

*/

@Override

protected void onSaveInstanceState(Bundle outState) {

super.onSaveInstanceState(outState);

}

/* 实际被销毁后恢复

* @see android.app.Activity#onRestoreInstanceState(android.os.Bundle)

*/

@Override

protected void onRestoreInstanceState(Bundle savedInstanceState) {

FragmentManager.clearCache();

ApplicationUtil.exit();

// printLog(Const.PATH_TEMP_ON_SD_CARD_OF_APP + "d.txt", "后台被杀死了/r/n");

  Intent intent =new Intent(this, ActivityLoading.class);

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(intent);

super.onRestoreInstanceState(savedInstanceState);

}
