我有一个接收调用广播接收器，它正在开发android 7.1坚果而不是Android 4.2。
广播接收器
public class CallReceiver extends BroadcastReceiver {
private MainActivity activity;
public static final String PREFS_PHONE = "Phone";
public static final String PREFS_EMAIL = "Email";
@Override
public void onReceive(Context context, Intent intent) {
Bundle extras = intent.getExtras();
SharedPreferences settings = context.getSharedPreferences(context.getResources().getString(R.string.app_name),0);
if(settings.contains(PREFS_EMAIL)) {
if (extras != null) {
String state = extras.getString(TelephonyManager.EXTRA_STATE);
Log.w("MY_DEBUG_TAG", state);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
DatabaseHandler db = new DatabaseHandler(context);
User user;
String phone = extras.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
try {
user = db.getUserByPhone(phone);
Log.d("USER", user.getEmail());
context.startActivity(new Intent(context, FloatingActivity.class)
.putExtra("PHONE", TelephonyManager.EXTRA_INCOMING_NUMBER));
String phoneNumber = extras
.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
settings.edit().putString(PREFS_PHONE, phone).apply();
Log.d("MY_DEBUG_TAG", phoneNumber);
} catch (IndexOutOfBoundsException e) {
Log.i(phone, "Not Found!");
}
}
}
}
}
}
浮动活动
public class FloatingActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chathead_layout);
startService(new Intent(this, FloatingViewService.class)
.putExtra("PHONE", this.getIntent().getStringExtra("PHONE")));
finish();

为什么不工作：
在7.1中，一切正常，我接到电话和聊天头。
在4.4 [LG]我接到电话但没有任何反应。
4.4 [BQ] Aplication崩溃。
任何帮助？
答案 0 :(得分：0)
发现问题。
我从以下活动之外调用startActivity：
context.startActivity(new Intent(context, FloatingActivity.class)
.putExtra("PHONE", TelephonyManager.EXTRA_INCOMING_NUMBER));
Intent.FLAG_ACTIVITY_NEW_TASK
o在所有的货币中，我需要称之为：
context.startActivity(new Intent(context, FloatingActivity.class)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
.putExtra("PHONE", TelephonyManager.EXTRA_INCOMING_NUMBER));
