android 10.0 以上隐藏方法无法调用 #Accessing hidden method

10.0 以上系统提示: Accessing hidden method********* 诸如此类的问题主要是Google 限制了隐藏方法通过反射调用,使用以下代码在,
业务代码调用前先执行可以解决以上问题。




if (SDK_INT < Build.VERSION_CODES.P) {
    return;
}
try {
    Method forName = Class.class.getDeclaredMethod("forName", String.class);
    Method getDeclaredMethod = Class.class.getDeclaredMethod("getDeclaredMethod", String.class, Class[].class);
    Class vmRuntimeClass = (Class) forName.invoke(null, "dalvik.system.VMRuntime");
    Method getRuntime = (Method) getDeclaredMethod.invoke(vmRuntimeClass, "getRuntime", null);
    Method setHiddenApiExemptions = (Method) getDeclaredMethod.invoke(vmRuntimeClass, "setHiddenApiExemptions", new Class[]{String[].class});
    Object sVmRuntime = getRuntime.invoke(null);
    setHiddenApiExemptions.invoke(sVmRuntime, new Object[]{new String[]{"L"}});
} catch (Throwable e) {
    Log.e("[error]", "reflect bootstrap failed:", e);
}
