android广播许可

java.lang.SecurityException:权限拒绝：不允许发送广播android.intent.action.DATE\u已从pid=3604、uid=10091更改

我犯了这样的错误 我搜索了一下，但找不到解决办法 请帮助……

试试这个

您不能使用

ACTION\u DATE\u CHANGED

，因为这是一个私有的android操作，所以您需要创建自定义操作

 var intent2 = Intent(requireActivity(), MyReceiver::class.java)
        intent2.putExtra("Test", "value")
        intent2.setAction(Intent.ACTION_DATE_CHANGED)





  override fun onReceive(context: Context, intent: Intent) {
            var st = intent.getStringExtra("Test")
        
            if (intent.action.equals(Intent.ACTION_DATE_CHANGED)) {
                var st = intent.getStringExtra("Test")
                var toast = Toast.makeText(context, st, Toast.LENGTH_LONG) //
                toast.show()
            }

}

当你打电话来分享你的信息时，请使用以下代码

private fun registerReceiver(){
        val filter = IntentFilter()
        filter.addAction(MyReceiver.RECEIVE_MESSAGE_ACTION)

        val customReceiver = MyReceiver()
        registerReceiver(customReceiver, filter)
    }

Intent.ACTION\u DATE\u CHANGED

是受保护的操作，只允许系统应用程序发送。那么我该怎么办？我刚开始，所以我不知道怎么做。

 <receiver
            android:name=".MyReceiver"
            android:exported="false">
            <intent-filter>
                <action android:name="${applicationId}.receiver.RECEIVE_MESSAGE_ACTION" />
            </intent-filter>
        </receiver>

private fun registerReceiver(){
        val filter = IntentFilter()
        filter.addAction(MyReceiver.RECEIVE_MESSAGE_ACTION)

        val customReceiver = MyReceiver()
        registerReceiver(customReceiver, filter)
    }

companion object {
        const val RECEIVE_MESSAGE_ACTION = "${BuildConfig.APPLICATION_ID}.receiver.RECEIVE_MESSAGE_ACTION"
    }

private fun callCustomBroadcast(message: String) {
        val intent = Intent(RECEIVE_MESSAGE_ACTION)
        intent.putExtra("mymessage", message)
        sendBroadcast(intent)
    }
