android - app keeps crashing on searching

so I've created an app which sets an alarm 25 mins before your departure time, based on the estimated time taken to travel from your place of departure to your destination.
I am able to build the app, but the app keeps crashing whenever I press the search button. I am guessing it has something to do with the integration of the placeautocomplete fragment, but not sure what about it.

Register broadcast receiver in android

I have register battery low broadcast receiver.
Like this
import com.save.sharedpreference.SharedPreference;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsManager;
import android.widget.Toast;
public class BootReceiver extends BroadcastReceiver {
String user_phone_key = "phone_number";
int last_level = 0;
#Override
public void onReceive(Context context, Intent intent) {
int rlevel = intent.getIntExtra("level", -1);
int scale = intent.getIntExtra("scale", -1);
int level = -1;
if (rlevel >= 0 && scale > 0) {
level = (rlevel * 100) / scale;
}
if (level == 48 && last_level == level + 1) {
SharedPreference save_data = new SharedPreference(
context.getApplicationContext());
String phone = save_data.get_string(user_phone_key, null);
Toast.makeText(context, "Level Decrease", Toast.LENGTH_SHORT)
.show();
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phone, null,
"Your Battery level is less ", null, null);
} catch (Exception e) {
Toast.makeText(context.getApplicationContext(),
"SMS faild, please try again later!", Toast.LENGTH_LONG)
.show();
e.printStackTrace();
}
}
last_level = level + 1;
}
}
Its working fine but the problem is when my battery level is reach 45% it start sending me sms until battery level change from 45%.
I want that when my battery level is reach 45% it just send me sms only one time and again waiting when battery level is 45%.
Is it possible?
Any help please.

Can you just use a local variable, like this?
public class BootReceiver extends BroadcastReceiver {
String user_phone_key = "phone_number";
int last_level = 0;
#Override
public void onReceive(Context context, Intent intent) {
int rlevel = intent.getIntExtra("level", -1);
int scale = intent.getIntExtra("scale", -1);
int level = -1;
if (rlevel >= 0 && scale > 0) {
level = (rlevel * 100) / scale;
}
if (level == 45 && last_level == 46) {
...
last_level = level;
}
}
I know it's not the most elegant solution, but it should work.
The more "official" solution is to use the ACTION_BATTERY_LOW intent to detect charge decreases, which IIRC only fires once, when the device hits low battery. Is there a reason you need to detect the battery level hitting 45%, in particular?

Create a boolean variable to send message only once.Like-
boolean isMsgSent=false;
and modify if loop as-
if(level==45 && !isMsgSent){
// send Msg
isMsgSent=true;
}
else{
isMsgSent=false;
}
It will send message only once when battery level is 45.

Activity crash if there is no entries

I have a problem. When there is entries stats activity works correctly. But If there is NO entries the stast activity crashes.
Please, help me. Need something to prevent it.
(I'm not programmer, so its not easy for me)
package com.sudarmuthu.android.wt.activities;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
import com.sudarmuthu.android.wt.R;
import com.sudarmuthu.android.wt.data.DBUtil;
import com.sudarmuthu.android.wt.data.Entry;
/**
* Activity class to handle stats
*
public class EntriesStatsActivity extends Activity {
// for debugging
private static boolean D = true;
private static String TAG = "WT - EntriesStatsActivity";
private List<Entry> mEntries;
/* (non-Javadoc)
* #see android.app.Activity#onCreate(android.os.Bundle)
*/
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.entry_stats);
Bundle bundle = getIntent().getExtras();
int typeId = bundle.getInt("typeId");
if (D) Log.d(TAG, "Got type id: " + typeId);
mEntries = DBUtil.fetchEntries(this, typeId, null);
Entry firstEntry = mEntries.get(0);
int count = mEntries.size();
float sum = 0;
float average = 0;
float min = Float.parseFloat(firstEntry.getValue());
float max = Float.parseFloat(firstEntry.getValue());
// calculate
for (Entry entry : mEntries) {
float value = Float.parseFloat(entry.getValue());
sum += value;
if (value < min) {
min = value;
}
if (value > max) {
max = value;
}
}
average = sum / count;
// populate the values
TextView statsCount = (TextView) findViewById(R.id.statsCount);
statsCount.setText("" + count);
TextView statsSum = (TextView) findViewById(R.id.statsSum);
statsSum.setText("" + sum);
TextView statsAverage = (TextView) findViewById(R.id.statsAverage);
statsAverage.setText("" + average);
TextView valueFrom = (TextView) findViewById(R.id.valueFrom);
valueFrom.setText("" + min);
TextView valueTo = (TextView) findViewById(R.id.valueTo);
valueTo.setText("" + max);
}
}

You may get a null pointer exception :
mEntries = DBUtil.fetchEntries(this, typeId, null);
if( mEntries == null ) {
return;
}

If there is no Entries, mEntries.size() is equals to 0. So when you do
average = sum / count;
You divide by 0, which throws an Arithmetic Exception(you can't divide a number by 0).

Android Send SMS from a Service? [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.
Closed 10 years ago.
I am trying to send SMS when the battery Level reached a particular value from a Service. I am not getting any errors but the SMS is not been sent.
MY CODE:
import android.app.Service;

String batteryNumber = "012345567";
String moderate=" Battery Level is 50 ";
String low = "Battery Level is low. Need to be charged immediately";
public IBinder onBind(Intent intent) {
return null;
}
public void onCreate() {
super.onCreate();
Toast.makeText(getApplicationContext(),"Service Running", Toast.LENGTH_SHORT).show();

if(batteryNumber!=null && level==49){

bat.sendTextMessage(batteryNumber,null,moderate,null,null);
}else if(batteryNumber!=null && level==20){
SmsManager bat = SmsManager.getDefault();
bat.sendTextMessage(batteryNumber, null,low, null, null);
}
}
}
LOGCAT:

03-09 03:41:40.390: E/NumberBattery(11086): Number is 01234567
Can you please tell what is wrong her?

It's because you never send the SMS.
When the following line is executed:
if (batteryNumber != null && level == 49){
level has not been initialized yet.
Change your code like this:
#Override
public void onReceive(Context context, Intent intent) {
level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE, -1);
voltage = intent.getIntExtra(BatteryManager.EXTRA_VOLTAGE, -1);
Log.e("BatteryManager", "level is "+level+"/"+scale+", temp is "+temp+", voltage is "+voltage);
Log.e("NumberBattery ", "Number is "+batteryNumber);
if (batteryNumber != null && level == 49) {
SmsManager bat = SmsManager.getDefault();
bat.sendTextMessage(batteryNumber,null,moderate,null,null);
} else if(batteryNumber!=null && level==20){
SmsManager bat = SmsManager.getDefault();
bat.sendTextMessage(batteryNumber, null,low, null, null);
}
}

Android-World Clock Widget analog

Can I use my own custom view in the widget, apart from analog clock? Or is there any other way to show the clock? like use the Imageview as the clock face and to draw the dial according to the time?
Please help me regarding this.!!!:(

You can create your own view and make the clock as well.

You can replaced the clock dial, clock hand minute and clock hand hour with your own drawings. Then You'll have your own custom clock.
android:dial="#drawable/YOUR_OWN_DIAL"
android:hand_hour="#drawable/YOUR_OWN_HOUR"
android:hand_minute="#drawable/YOUR_OWN_MINUTE"
Test the layout in the Graphical Layout Tool to see how it look like.
