出现该弹窗的原因是Android P禁止了非官方API的调用，如果你用了一些别的sdk接口，就会有这样的弹窗问题。
解决方法是，通过反射在不让系统弹出这个窗口：
//application.java
private void closeAndroidPDialog(){
try {
Class aClass = Class.forName("android.content.pm.PackageParser$Package");
Constructor declaredConstructor = aClass.getDeclaredConstructor(String.class);
declaredConstructor.setAccessible(true);
} catch (Exception e) {
e.printStackTrace();
}
try {
Class cls = Class.forName("android.app.ActivityThread");
Method declaredMethod = cls.getDeclaredMethod("currentActivityThread");
declaredMethod.setAccessible(true);
Object activityThread = declaredMethod.invoke(null);
Field mHiddenApiWarningShown = cls.getDeclaredField("mHiddenApiWarningShown");
mHiddenApiWarningShown.setAccessible(true);
mHiddenApiWarningShown.setBoolean(activityThread, true);
} catch (Exception e) {
e.printStackTrace();
}
}
