问题描述
我的应用是自动呼叫记录器，在版本9之前可以正常使用，但在上面崩溃 有人接听电话时出现应用程序崩溃，并给出了无法启动接收器的错误，这两个类都包含错误图像。接收者选择来电时，应用程序崩溃，功能调用getAbsolutePath（）上出现错误

并且Receiver扩展类是
public class Receiver_Extended extends Receiver_store {
String formated_number;
@Override
protected void onIncomingCallStarted(Context ctx,Date start) {
//incoming call ringing
}
@Override
protected void onOutgoingCallStarted(Context ctx,Date start) {
//out going call started
formated_number= Utils_String.prepareContacts(ctx,number);
SharedPreferences SP = PreferenceManager.getDefaultSharedPreferences(ctx);
boolean b=SP.getBoolean("STATE",true);
if (b&& GetContact.checkContactToRecord(ctx,number)){
startRecord(formated_number+"__"+ GetContact.getCurrentTimeStamp()+"__"+"OUT__2");
addtoDatabase(ctx,formated_number);
GetContact.sendnotification(ctx);
}
}
@Override
protected void onIncomingCallAnswered(Context ctx,Date start) {
//incoming call answered
formated_number= Utils_String.prepareContacts(ctx,true);
if(b&& GetContact.checkContactToRecord(ctx,number)){
startRecord(formated_number+"__"+ GetContact.getCurrentTimeStamp()+"__"+"IN__2");
addtoDatabase(ctx,formated_number);
GetContact.sendnotification(ctx);
}
}
@Override
protected void onIncomingCallEnded(Context ctx,Date end) {
//incoming call ended
SharedPreferences SP = PreferenceManager.getDefaultSharedPreferences(ctx);
boolean b=SP.getBoolean("STATE",true);
if(b){
stopRecording();
}
notificationmanager notificationmanager=(notificationmanager)ctx.getSystemService(Context.NOTIFICATION_SERVICE);
notificationmanager.cancelAll();
GetContact.sendnotificationOnEnd(ctx);
}
@Override
protected void onOutgoingCallEnded(Context ctx,Date end) {
//outgoing call ended
SharedPreferences SP = PreferenceManager.getDefaultSharedPreferences(ctx);
boolean b=SP.getBoolean("STATE",true);
if(b){
stopRecording();
}
notificationmanager notificationmanager=(notificationmanager)ctx.getSystemService(Context.NOTIFICATION_SERVICE);
notificationmanager.cancelAll();
GetContact.sendnotificationOnEnd(ctx);
}
@Override
protected void onMissedCall(Context ctx,Date start) {
//miss call
}
public void addtoDatabase(Context ctx,String number){
DatabaseHelper db=new DatabaseHelper(ctx);
if(db.isContact(number).getNumber()!=null){
}else{
Contacts_data contacts=new Contacts_data();
contacts.setFav(0);
contacts.setState(0);

}
}
