[FAQ19142]VOIP APK与普通电话交互导致普通电话无声

来源：互联网发布：淘宝突然登不上去了编辑：程序博客网时间：2024/05/17 01:31

[DESCRIPTION]

先进行What's APP通话，然后普通电话来电接听，再返回What's APP界面，普通电话无声，What's APP声音恢复

正常来说普通电话应该比What's APP重要，普通电话时不应该允许恢复VOIP电话

[SOLUTION]

在AudioService.java setMode()接口中增加相关判断，如果当前是普通电话模式时，则不允许切换到VOIP Mode

具体Code修改如下：

public void setMode(int mode, IBinder cb) {

if (DEBUG_MODE) { Log.v(TAG, "setMode(mode=" + mode + ")"); }

if (!checkAudioSettingsPermission("setMode()")) {

if (DEBUG_VOL) Log.e(TAG, "setMode: No permission!");

return;

}

//AAAA Add begin

if((mode == AudioSystem.MODE_IN_COMMUNICATION) && ( (mMode == AudioSystem.MODE_IN_CALL) || (mMode == AudioSystem.MODE_IN_CALL_2)))

{

Log.w(TAG, "MODIFY_PHONE_STATE Permission Denial: Current mode is in call");

return;

}

//AAAA Add end

if ( (mode == AudioSystem.MODE_IN_CALL) &&

(mContext.checkCallingOrSelfPermission(

android.Manifest.permission.MODIFY_PHONE_STATE)

!= PackageManager.PERMISSION_GRANTED)) {

Log.w(TAG, "MODIFY_PHONE_STATE Permission Denial: setMode(MODE_IN_CALL) from pid="

+ Binder.getCallingPid() + ", uid=" + Binder.getCallingUid());

return;

}

if (mode < AudioSystem.MODE_CURRENT || mode >= AudioSystem.NUM_MODES) {

if (DEBUG_VOL) Log.e(TAG, "setMode: Invalid mode!");

return;

}

//#ifdef VENDOR_EDIT

//Yujie.Wei@EXp.GeneralApp.audio. 2016/03/16, add for judge whether voip call

Intent broadcast = new Intent("android.media.OPPO_VOIP");

if(AudioManager.MODE_IN_COMMUNICATION == mode) {

broadcast.putExtra("android.media.OPPO_VOIP_EXTRA", 1);

}

else{

broadcast.putExtra("android.media.OPPO_VOIP_EXTRA", 0);

}

sendBroadcastToAll(broadcast);

//#endif /* VENDOR_EDIT */

int newModeOwnerPid = 0;

synchronized(mSetModeDeathHandlers) {

if (mode == AudioSystem.MODE_CURRENT) {

mode = mMode;

}

newModeOwnerPid = setModeInt(mode, cb, Binder.getCallingPid());

}

// when entering RINGTONE, IN_CALL or IN_COMMUNICATION mode, clear all

// SCO connections not started by the application changing the mode

if (newModeOwnerPid != 0) {

disconnectBluetoothSco(newModeOwnerPid);

}
