Question

我写了一个BroadcastReceiver课程，用于在充电器断开时接收广播意图，但在断开充电器时它不会显示Toast。 Logcat也没有显示任何内容。我在wifi上使用ADB。

请帮忙

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class My extends BroadcastReceiver {

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        Toast.makeText(arg0, "hello", Toast.LENGTH_LONG).show();
    }

}

这是我的清单

将您在Android清单中的操作更改为：

Cipher cipher = Cipher.getInstance("RSA");
