我的App Drive Drive可以找到here。 Drive Safe是一款免费应用程序，可防止分心驾驶。当应用程序启动时，它会自动回复给您打电话或发短信的任何人。
我有2个测试手机，它在它们上运行得很完美，并且在朋友的手机上进行了测试，在这个阶段最多可以测试20个，而且它也很适合它们，但是我收到了来自世界各地的人的电子邮件告诉我，Drive Safe并不适合他们。要么根本不工作，只能将电话置于静音状态，要么对其他回复电话而不是文本，对其他人则不然。 我已经改变了一些我认为可能是问题区域的代码，但我仍然收到来自新人的电子邮件说他们遇到了问题。
我不确定该应用有多少人使用的百分比，即10％，％50，％80或％90。我可以看到我在上周有近1000个会话和762个用户返回用户。
我的应用主要在后台运行，并使用服务。也是一个收听短信和电话的广播接收器。
这是我的一些代码： 按钮的代码，用于关闭应用程序或关闭。
// listen for clicks on the main button
buttonToggleDetect.setOnClickListener(new View.OnClickListener() {
@Override
// when the main button is clicked
public void onClick(View v) {
setDetectEnabled(!detectEnabled);
mTracker.send(new HitBuilders.EventBuilder()
.setCategory("Home")
.setAction("Share")
.build());
if (detectEnabled) {
showStatusBarIcon(true);
} else
showStatusBarIcon(false);
}
});
用于在按下主按钮时关闭服务的代码
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
private void setDetectEnabled(boolean enable) {
detectEnabled = enable;
Intent intent = new Intent(this, CallDetectService.class); //creating a new intent to be sent to CallDetectService class
SharedPreferences sharedPreferences = getSharedPreferences("driveSafeMode", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("mode", enable);
editor.apply();
if (enable) {
startService(intent);
setRingerSilent();
} else {
// stop detect service
stopService(intent);
setRingerNormal();
}
toggleUI();
}
Call Helper类，用于处理收到的呼叫并将文本发送回传入的号码。
private String phoneNumber ="0";
private int count=0;
private Boolean messageSent = false;
private final BroadcastReceiver mybroadcast = new IncomingSms();
public CallHelper() {}
// Listener to detect incoming calls.
public class CallStateListener extends PhoneStateListener{
@Override
public void onCallStateChanged (int state, String incomingNumber) {
switch (state){
case TelephonyManager.CALL_STATE_RINGING:
// case when someone is calling the users phone
//Creating a object of the AudioManager Class
AudioManager audioManager = (AudioManager) ctx.getSystemService(Activity.AUDIO_SERVICE);
// Emergency mode code is below till 2nd else statement
// Emergency mode is when a person calls 3 times in a row, on the third time
// the app will be switched off and the phone will ring aloud.
// if the saved variable phoneNumber is == to the current incoming number trigger if
if (phoneNumber.equalsIgnoreCase(incomingNumber)) {
count++;
if (count >=2){
// stop app
ctx.stopService(new Intent(ctx, CallDetectService.class));
stop();
Toast.makeText(ctx, R.string.emergencyModeString, Toast.LENGTH_LONG).show();
phoneNumber = "0";
audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
count = 0;
} else {
// this is to prevent the Drive Safe Message being sent muliple times in receipt of one text/call
// Drive safe Message should only be sent once per message or call
if (!messageSent) {
SendMessage();
messageSent = true;
}
}
} else {
phoneNumber = incomingNumber.toString();
if (!messageSent) {
SendMessage();
messageSent = true;
// if the phone is not == to previous incoming call and
// the Drive Safe Message has not already been sent, send it.
}
}
break;
// whent the phone is not ringing and in a idle state set messageSent = to false
case TelephonyManager.CALL_STATE_IDLE:
messageSent = false;
}
}
}
private Context ctx;
private TelephonyManager tm;
private CallStateListener callStateListener;
// Constructor
public CallHelper(Context ctx){
this.ctx = ctx;
tm = (TelephonyManager) ctx.getSystemService(Context.TELEPHONY_SERVICE);
callStateListener = new CallStateListener();

//Method
public void SendMessage(){
String sms = MainActivity.driveSafeSms;
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNumber, null, sms, null, null);

// Stop Call Dectection

CallDetectService这是服务类
// create instance of CallHelper class
private CallHelper callHelper;
private final BroadcastReceiver mybroadcast = new IncomingSms();
IntentFilter filter = new IntentFilter();
private Boolean listeningSms = false;
public CallDetectService() {}
@Override
public int onStartCommand(Intent intent, int flags, int startId){
//Register Broadcast Reciever
//if the sms BroadcastReceiver has not already been registered register it
if (!listeningSms) {
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(mybroadcast, filter);
listeningSms = true;
}
callHelper = new CallHelper(this);
int res = super.onStartCommand(intent, flags, startId);
callHelper.start();
return res;
}
@Override
public void onDestroy(){
super.onDestroy();
callHelper.stop();
// if the sms broadcast reciever has been registered, unregister it
if (listeningSms == true) {
unregisterReceiver(mybroadcast);
listeningSms = false;
}
Toast.makeText(getApplicationContext(), R.string.inActive, Toast.LENGTH_SHORT).show();
}
@Override
public IBinder onBind (Intent intent) {
return null;
}
}
