我正在创建一个运行服务的应用程序来捕获传出和传入的调用，并根据数字执行一些逻辑！
但是，当我第一次启动应用程序（安装后的示例）并退出应用程序并尝试呼叫时，电话状态监听器调用CALL_STATE_IDLE而不是CALL_STATE_OFFHOOK。但是从第二次调用本身开始按预期工作！当系统重新启动并在此之后第一次调用时也会发生这种情况！我使用BootCompleteReceiver广播接收器！
为什么会这样？请在这里建议修复！
我的服务代码：
public class CallService extends Service{
PreferenceHelper finalprefs;
Boolean updated = true;
@Override
public void onCreate() {
super.onCreate();
if (Build.VERSION.SDK_INT >= 26) {
Notification notification=new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentText("").build();
startForeground(1, notification);
}
Log.e("SERVICE","STARTED");
IntentFilter filter = new IntentFilter();
filter.addAction("android.intent.action.PHONE_STATE");
finalprefs = new PreferenceHelper(getApplicationContext(),"1",0);
registerReceiver(receiver, filter);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
if(isMyServiceRunning(CallService.class)){
}
else{
unregisterReceiver(receiver);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
Log.e("> Nougout","> Nougout");
//Util.scheduleJob(getApplicationContext());
startForegroundService(new Intent(getApplicationContext(), CallService.class));
}
else {
startService(new Intent(getApplicationContext(), CallService.class));
}
}
Log.e("DESTROYED","sdsadasdasdasd");
}
@Override
public void onTaskRemoved(Intent rootIntent) {
Log.e("onTaskRemoved","sdsadasdasdasd");
if(isMyServiceRunning(CallService.class)){
}
//startService(new Intent(getApplicationContext(), CallService.class));
else{
unregisterReceiver(receiver);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
Log.e("> Nougout","> Nougout");
//Util.scheduleJob(getApplicationContext());
startForegroundService(new Intent(getApplicationContext(), CallService.class));
}
else {
startService(new Intent(getApplicationContext(), CallService.class));
}
}
super.onTaskRemoved(rootIntent);
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
private final BroadcastReceiver receiver = new BroadcastReceiver() {
String number ="";
TelephonyManager telManager;
Context context;
boolean startedCall = false;
boolean endedCall = false;
int ring = 0;
@Override
public void onReceive(Context context, Intent intent)
{
this.context=context;
boolean startedCall = false; // New added boolean
telManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
telManager.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
}
private final PhoneStateListener phoneListener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
try {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING: {
//INCOMING CALL
if(incomingNumber!=null && ring <= 0) {
bussinessLogic(incomingNumber);
ring++;
Log.e("CALL_STATE_RINGING","CALL_STATE_RINGING");
}
break;
}
case TelephonyManager.CALL_STATE_OFFHOOK: {
//Outgoing call
Log.e("OUTGOING CALL","CALL NUMBER - "+incomingNumber);
startedCall = true; // Newly added code
if(incomingNumber!=null) {
if(incomingNumber.equals("#8678")){
disconnectPhoneItelephony(context);
if(finalprefs.getBoolean("hidden",false)){
Intent i = new Intent(getApplicationContext(),PinverificationHidden.class);
startActivity(i);
}
else{
Intent i = new Intent(getApplicationContext(),Pinverification.class);
startActivity(i);
}
}
else{
bussinessLogic(incomingNumber);
}
Log.e("CALL_STATE_OFFHOOK","CALL_STATE_OFFHOOK");
}
break;
}
case TelephonyManager.CALL_STATE_IDLE: {
//CALL DISCONNECTED
ring = 0;
Log.e("CALL_STATE_IDLE --","CALL_STATE_IDLE --");
if(startedCall) {
Log.e("CALL_STATE_IDLE","CALL_STATE_IDLE");
}
break;
}
default: {
break;
}
}
} catch (Exception ex) {
}
//telManager.listen(phoneListener, PhoneStateListener.LISTEN_NONE);
}
};
}
我在活动开始时开始这项服务！此外，我在PHONE STATE的广播接收器中开始此活动！
我的BoradcastReciever是：
public class CallBarring extends BroadcastReceiver
{
PreferenceHelper finalprefs;
// This String will hold the incoming phone number
private String number;
@Override
public void onReceive(Context context, Intent intent)
{
finalprefs = new PreferenceHelper(context,"1",0);
// If, the received action is not a type of "Phone_State", ignore it
if (!intent.getAction().equals("android.intent.action.PHONE_STATE"))
return;
else
{
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
Log.e("> RECIEVER","> RECIEVER");
if(!isMyServiceRunning(context)){
context.startForegroundService(new Intent(context, CallService.class));
}
}
else{
if(!isMyServiceRunning(context)){
context.startService(new Intent(context, CallService.class));
}
}
}
}
}
当你启动Service时，它会注册BroadcastReceiver，但不会注册PhoneStateListener。您只在PhoneStateListener被触发后注册了BroadcastReceiver（由于电话状态改变）。此时，您注册了PhoneStateListener，但您将错过第一次手机状态更改。这就是它第一次不起作用的原因。
