在Android 6.0中回答来电

Question

有没有办法在没有root权限的情况下以编程方式回答Android 6.0中的来电？我尝试了以下方法:

1. 内部ITelephony.aidl方法 - 有了这个我能够结束通话.但是接听电话需要android.permission.MODIFY_PHONE_STATE在Android 6.0中未提供给第三方应用.
2. 耳机KeyCode意图方法.这根本不起作用.

希望这会有所帮助:)

经过大量搜索后，我发布了在 Orasi 中使用的代码。希望这对很多程序员有所帮助...注意此代码是从具有其他功能的软件中提取的，因此某些代码可能并不在所有软件中使用。

首先，在所有 Android 版本上接听和结束通话的功能（没有 AIDL！）：

\n\n

\n\n

二、权限：

\n\n

    if(Build.VERSION.SDK_INT >= 26) { // Permission necessaire\n        if(checkSelfPermission("android.permission.ANSWER_PHONE_CALLS") != PackageManager.PERMISSION_GRANTED) {\n            String szPermissions[] = {"android.permission.ANSWER_PHONE_CALLS"};\n            requestPermissions(szPermissions, 0);\n        }\n    }\n

\n\n\n\n

    if(Build.VERSION.SDK_INT >= 23 && bUseScreen ) { // Permission necessaire\n        if(checkSelfPermission("android.permission.SYSTEM_ALERT_WINDOW") != PackageManager.PERMISSION_GRANTED) {\n            Intent myIntent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);\n            startActivity(myIntent);\n        }\n        if(Build.VERSION.SDK_INT < 26) { // Permission pour Android 6.x et 7.x\n            ContentResolver contentResolver = getContentResolver();\n            String enabledNotificationListeners = Settings.Secure.getString(contentResolver, "enabled_notification_listeners");\n            String packageName = getPackageName();\n            if (enabledNotificationListeners == null || !enabledNotificationListeners.contains(packageName)) {\n                Intent intent2 = new Intent(Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS);\n                startActivity(intent2);\n            }\n        }\n    }\n

\n\n

注意，有Overlay的权限，不能直接接听电话。

\n\n

通知接收服务：

\n\n

package mss.micromega.pmignard.orasi;\n\nimport android.annotation.SuppressLint;\nimport android.annotation.TargetApi;\nimport android.os.Build;\nimport android.service.notification.NotificationListenerService;\n\n@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2)\n@SuppressLint("OverrideAbstract")\npublic class NotificationReceiverService extends NotificationListenerService {\n    public NotificationReceiverService() {\n    }\n}\n

\n\n

显现：

\n\n

    <service android:name=".NotificationReceiverService"\n             android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"\n             android:enabled="true"\n             android:exported="true" >\n            <intent-filter>\n                <action android:name="android.service.notification.NotificationListenerService" />\n            </intent-filter>\n    </service>\n

\n\n\n\n

<uses-permission android:name="android.permission.ANSWER_PHONE_CALLS"/>\n<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>\n

\n\n

问候。
