My app keeps crashing

Question

I made an app in eclipse and it keeps on crashing every time i want to open it.The app is supposed to be able to make the phone turn off when a specifically worded text message is received.It does require root privileges.Also the way i am running it is by pressing the run button on eclipse,and it show that i have no error in the coding so as you can see i am very lost.

Here is the log file:

sorry didnt notice i deleted the other can any of you help me? — user2250077, Apr 05 '13 at 23:40
How do you not notice you posted the same large chunk of code and XML twice? You posted a couple of hundred lines in each place - pretty hard not to notice you're doing that, isn't it? :-) — Ken White, Apr 05 '13 at 23:44
i thought i was editing the other one but i wasnt becuz i copied and pasted my log file — user2250077, Apr 05 '13 at 23:46

java.lang.ClassNotFoundException: Didn't find class "com.rabazid.abzsmspoweroff.SmsLoggerActivity"

You are missing the Class definition I assume.

Sorry but i have to ask.What is the class definition and how do i add it? – user2250077 Apr 05 '13 at 23:45
Where is your `SmsLoggerActivity` ? Have you defined it ? – Swayam Apr 05 '13 at 23:46
This is the only log i got was that one and another one but that one has everything that ran on the system not the app – user2250077 Apr 05 '13 at 23:49
You did not get me. I am asking you if you have defined your `SmsLoggerActivity.java` file ? – Swayam Apr 05 '13 at 23:52
i dont think so? how can i figure out if i did? – user2250077 Apr 05 '13 at 23:55
Well, go to the `src` folder and see if you have `SmsLoggerActivity.java` there or not ? – Swayam Apr 05 '13 at 23:56
all i have is SMSReceiver.java in there – user2250077 Apr 06 '13 at 00:02
*Bingo!* I knew it! So, see the thing is that you do not have any Activity defined but your manifest has a `SmsLoggerActivity`. So you need to create a SmsLoggerActivity.java. I suggest you to go through the basic tutorials of Android to understand the concepts. – Swayam Apr 06 '13 at 00:04
http://shreymalhotra.me/blog/tutorial/receive-sms-using-android-broadcastreceiver-inside-an-activity/ – Swayam Apr 06 '13 at 00:07
can you give me a link to that tutorial? – user2250077 Apr 06 '13 at 00:09
And for the basics, please go through http://developer.android.com/training/index.html – Swayam Apr 06 '13 at 00:12
ok so i added it,now another question in my code where do i type the keyword that makes the phone turn off? – user2250077 Apr 06 '13 at 00:25
@user2250077 : You cannot switch off the phone, as far as I know. Have a look here for further details : http://stackoverflow.com/questions/3745523/programmatically-switching-off-android-phone – Swayam Apr 06 '13 at 06:15

This is most likely a build problem

If you are building this code using a build machine then chances are that the code is being excluded in the build process.

If you are not using a build machine.. then one thing you can try is delete the bin/gen directory and regenerate all the files. If you look in the bin directory and follow the com.rabazid.abzsmspoweroff.SmsLoggerActivity path, then you will see if its being included in your apk. Everything in the bin directory is what is used applied to the final binary. Also another thing to check would be your proguard rules.

If all is well then, then you should see com.rabazid.abzsmspoweroff.SmsLoggerActivity in its respective path.

nope i dont have the sms loggeractivity path do you know how i can add it? – user2250077 Apr 05 '13 at 23:51
You need to find out why its not appearing. Ideally the ADT tools should be compiling your classes into binaries and then throwing them in bin in their respective folder. Check the package name of that class and ensure that it matches the reference. If you could post the top part of your SmsLoggerActivity. – JoxTraex Apr 05 '13 at 23:55
@JoxTraex : I have a feeling that he hasn't defined his Activity class in java. – Swayam Apr 05 '13 at 23:57
Looking at the manifest, I do see the refference to SmsLoggerActivity @swayam – JoxTraex Apr 05 '13 at 23:58
Yeah, I know. That is why I said "in java". Look at the comments on my answer. I don't think he has a proper SmsLoggerActivity. Could have just entered the name of the Activity during the creation of the project. – Swayam Apr 06 '13 at 00:00
all i have is SMSReceiver.java in there – user2250077 Apr 06 '13 at 00:03
we are talking about SmsLoggerActivity not SMSReceiever. But yes, that could be possible, you may not have the SmsLoggerActivity java file, if thats the case then thats why its not generating that class file. – JoxTraex Apr 06 '13 at 00:04

@JoxTraex : He only has the SMSReceiver. That is why the Activity is not found. – Swayam Apr 06 '13 at 00:05
so how can i make a SmsLoggerActivity java file? – user2250077 Apr 06 '13 at 00:05
Make an activity file that is called SmsLoggerActivity. – JoxTraex Apr 06 '13 at 00:08
ok so i added it,now another question in my code where do i type the keyword that makes the phone turn off? – user2250077 Apr 06 '13 at 00:27
