Java Android Studio应用程序停止工作
我可以在我的项目中放多少活动多少张图片？我做了一个项目，现在有13个活动，当我有5到8个活动时，我的项目运行得非常好。没有堆叠，没有崩溃，现在我有13个活动，当我构建我的项目并打开它时，欢迎屏幕工作，我可以打开一个、两个或三个其他活动，但打开4个或5个活动，我的应用程序停止工作并崩溃。我认为这是内存不足，但我不明白为什么会发生这种情况，因为我已经调整了所有位图的大小并对其进行了压缩，当我在Java Android Studio应用程序停止工作,java,android,Java,Android,我可以在我的项目中放多少活动多少张图片？我做了一个项目，现在有13个活动，当我有5到8个活动时，我的项目运行得非常好。没有堆叠，没有崩溃，现在我有13个活动，当我构建我的项目并打开它时，欢迎屏幕工作，我可以打开一个、两个或三个其他活动，但打开4个或5个活动，我的应用程序停止工作并崩溃。我认为这是内存不足，但我不明白为什么会发生这种情况，因为我已经调整了所有位图的大小并对其进行了压缩，当我在startActivity（）之后启动新活动时，我将finish（） 下面是nocnizivotActivi

AFAIK支持13个活动，所以我想问题出在其他地方。也许你没有给你的AVD足够的内存。
无论如何，我建议您使用fragment。试试看，这可能会帮助您在清单文件中添加此标记
<application
...
...
android:largeHeap="true"
......
......
</application>
选中此项在实际设备上测试您的应用程序，它将工作共享崩溃消息和日志。当我在android手机上测试它时，它工作正常，但在打开3或4个活动后，它将停止。。。
Bitmap bm;
bm = Bitmap.createScaledBitmap(BitmapFactory.decodeFile(filepath),100, 100, true);
mPicture = new ImageView(context);
mPicture.setImageBitmap(bm);
