错误日志 在网上找了各种回复都没有一个具体的答案 导致的问题是 多次进入rn面板然后实例未销毁的内存卸载白屏返回原生的页面
具体的方式是因为在安卓提供的module中存在问题
原生module extends ReactContextBaseJavaModule implements LifecycleEventListener,
重写以下四个个方法
@Override
public void onHostResume() {
//尽量不要在这里进行监听操作 即使添加了 需要在下面的方法中销毁 不然会报错
register failed , the sensor listeners size has exceeded the maximum limit 128
之前在这里注册了遇到了这个问题 没有及时销毁导致报错
}
@Override
public void onHostPause() {
}
@Override
public void onHostDestroy() {
}
//必须重写销毁实例
@Override
public void onCatalystInstanceDestroy() {
super.onCatalystInstanceDestroy();
}
这样就可以避免白屏的问题了
