[移动开发]Activity 异常重启，删除缓存的Fragment

public static void removeAllFragments(FragmentActivity context){
    FragmentManager fragmentManager = context.getSupportFragmentManager();
    FragmentTransaction transaction = fragmentManager.beginTransaction();
    List<Fragment> fragmentList = fragmentManager.getFragments();
    if(fragmentList == null || fragmentList.isEmpty()){
        Log.e("test", context + " no old Fragment, fragmentList = " + fragmentList );
        return;
    }
    for (Fragment f : fragmentList) {
        transaction.remove(f);
        Log.e("test", context + " delete old Fragment : " + f);
    }
    transaction.commitNow();
    //transaction.commit();
}

使用

MainActivity.java

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FragmentUtil.removeAllFragments(this);

}
