优化启动屏幕内存

但我注意到,即使我完成了活动,内存使用量也增加了很多,有背景的splash和没有背景的splash之间的内存使用量有很大差异。

有什么解决办法吗?

splash没有背景图像时的内存捕获

splash活动的代码

public class SplashActivity extends AppCompatActivity {

    /**
     * To get ride of the activity reference to avoid memory leaks
     */
    private static WeakReference<SplashActivity> mActivity;

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

        mActivity = new WeakReference<>(this);

        //delay for 2 seconds and start the home activity
        Completable.complete()
                .delay(2, TimeUnit.SECONDS)
                .doOnComplete(this::startHomeActivity)
                .subscribe();
    }

    private void startHomeActivity() {
        if (mActivity.get() != null) {
            Activity activity = mActivity.get();
            Intent homeIntent = new Intent(activity, HomeActivity.class);
            startActivity(homeIntent);
            activity.finish();
        }
    }
}

<style name="splashScreenTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowBackground">@drawable/zamen_splash</item>
