通过线程打开活动导致崩溃

Question

对于活动A和B，我在清单中设置了属性android:noHistory = true。 活动B相当重，这就是为什么我在线程中调用意图打开该活动的原因，但问题是加载整个应用程序后只是崩溃和着名的意外错误使用Force close按钮发生。任何解决方案都表示赞赏。

这里有活动A：

public class FirstActivity extends Activity {

    private static int PROGRESSSECONDS = 4;
    private static Handler FirstActivityHandler;
    private ProgressBar pb;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_first);

        FirstActivityHandler = new Handler(){
            @Override
            public void handleMessage(Message msg) {
                pb.setProgress(msg.arg1);
            }
        };
    }

    public void PlayNowAction(View v) {
        setContentView(R.layout.loadingscreen);
        pb = (ProgressBar) findViewById(R.id.pbLoader);
        pb.setMax(PROGRESSSECONDS);
        pb.setProgress(0);

        new Thread(new Runnable() {

            @Override
            public void run() {
                try {
                    for (int i = 1; i <= PROGRESSSECONDS; i++) {
                        Thread.sleep(1000);
                        Message msg = Message.obtain();
                        msg.arg1 = i;
                        FirstActivityHandler.sendMessage(msg);
                    }

                } catch (InterruptedException e) {

                } finally {
                    Intent in = new Intent(FirstActivity.this,
                            PointsDrawerActivity.class);
                    startActivity(in);
                }
            }
        }).start();

    }
}

这里有活动B：

public class PointsDrawerActivity extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_first);

        addReccords(); // this a working method but it takes very long time
    }

}

这是我的LogCat：

我担心实际问题是使用位图。您的应用程序遭受了臭名昭着的OutOfMemoryError，如果您的应用程序与几个位图有任何关系，这注定会发生。有必要处理它们。这是一种方法： OutOfMemoryError resolution
