反应本机相机不会在第二次调用时工作

Question

React 原生相机在 Android 中的第二次调用中不起作用。在第二次调用时，应用程序崩溃。我在用 本机反应：0.56.0 反应原生相机：1.6.4 当我使用最新版本的 react-native-camera 时也是如此。我无法将 react-native 更新到最新版本，因为我有另一个与最新版本不兼容的包 它在模拟器上工作正常，只有真实设备有问题

The --scan result is

我收到这个错误是因为我没有存储空间来保存拍摄的图像。要使其工作，请将其添加到 AndroidManifest.xml 文件

android:largeHeap="true"
