安卓内存不足错误：Java堆内存（GC堆）

Question

突然我的应用程序崩溃并弹出此错误。。。你知道这个错误吗？这么努力还是解决不了

我试过像this、this和this这样的东西，但不起作用

有人能帮我解决吗？我真的很感激

谢谢

在Manifext.xml中添加这一行android:largeHeap="true"它将分配一个大的堆内存

<application
        android:name=".MyApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"

        android:largeHeap="true"

        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/MyAppTheme">
...
</application>

我希望这对你有用

尝试使用调试器和Android Profiler来检测用于提高性能的资源的确切位置
