Question

我有这段代码，但我的应用程序未检测到来电。

我的代码与这个答案非常相似我做错了什么？

How does a Android "OS" detect a incoming call

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.reporting2you.r2ym">

    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <service
            android:name="com.reporting2you.services.FloatingViewService"
            android:enabled="true"
            android:exported="false" />

        <activity android:name=".FloatingActivity" />

        <receiver
            android:name="com.reporting2you.broadcastReceiver.CallReceiver"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
        </receiver>
    </application>

</manifest>

广播接收器

public class CallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();
        if (extras != null) {
            String state = extras.getString(TelephonyManager.EXTRA_STATE);
            Log.w("MY_DEBUG_TAG", state);
            if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
                context.startActivity(new Intent(context, FloatingActivity.class));
                ((MainActivity)context).finish();
                String phoneNumber = extras
                        .getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
                Log.w("MY_DEBUG_TAG", phoneNumber);
            }
        }

    }
}

Answer 1

如果您使用 android.intent.action.PHONE_STATE，您需要先请求 READ_PHONE_STATE 许可。因为android.permission.READ_PHONE_STATE是危险级别权限，所以必须在运行时间内checkSelfPermission()。

否则，当运行在具有 Android 版本高于 Marshmallow (23) 的设备上时，将不会触发广播。

Answer 2

尝试

public class CallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();
        if (extras != null) {
            String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE); //Change Here
            Log.w("MY_DEBUG_TAG", state);
            if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
                context.startActivity(new Intent(context, FloatingActivity.class));
                ((MainActivity)context).finish();
                String phoneNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER); //Change Here
                Log.w("MY_DEBUG_TAG", phoneNumber);
            }
        }

    }
}
