i searched for way to store a global variables that will be shared with all the activities.
i found this:
How to declare global variables in Android?
and i created a class that extends application and i declare this application in the manifest file.
however i have a problem:
i cant decalre more than one application in the manifest file...
therefore if i want to declare two applications, what can i do?
here is my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sa"
android:versionCode="1"

<activity android:name="AllItemsActivity"></activity>
<activity android:name="itemCategory"></activity>
<activity android:name="ItemMapActivity"></activity>
</application>
</manifest>
and i also want to delare a class that extends application that will store the shared variables:
<application android:name="MyApp"
android:icon="#drawable/icon"
android:label="#string/app_name2"></application>
and this is the class:
class MyApp extends Application {
private String myState;
public String getState(){
return myState;
}
public void setState(String s){
myState = s;
}
}
class Blah extends Activity {
#Override
public void onCreate(Bundle b){
...
MyApp appState = ((MyApp)getApplicationContext());
String state = appState.getState();
...
}
}
thanks alot
You can not declare more than one application.
You can have more variables in you application, but application is a singleton class.
To define Global Variable you can make use of static Keyword:
public static String myState;

I'm trying to put an app on google and they reject it in addition to not giving me a concrete answer.
It's an SMS-sending app. I don't keep any user data.
The user fills in 3 fields and is sent to a predefined toll-free number, which sends a reply.
The part of the number and the answer is not up to the app: it is just to facilitate the user's work.
Here is my manifest:
<?xml version="1.0" encoding="utf-8"?>

I'm trying to integrate flurry into my android app. I'm using the recommended setting and have repositories{jcenter()} and
// Required for Flurry Analytics integration
compile 'com.flurry.android:analytics:8.2.0#aar'
// Optional - If you want to use the Ads SDK
compile 'com.flurry.android:ads:8.2.0#aar'
in the gradle as the docs suggest. I keep getting errors in the that Application is not resolved. The docs really blow and I'm not 100% sure what going on. I've never integrated flurry before can someone please help! I put the manifest and the class i'm using below. I know it doesn't have a key I'm still working on removing errors. I'm dumping the that class in the main file for simplicity for now.
<?xml version="1.0" encoding="utf-8"?>

Declare the application name in manifest.xml file.

</intent-filter>
</activity>
</application>
my application crashes at start and I have no idea why. I'm testing it on a real device (Samsung Galaxy S3 GT-I9300). Here is the exception:
EDIT:
So, that's what I've added to onCreate():
walking.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
travel_mode = "walking";
walking.setImageResource(R.drawable.walking_sel);
biking.setImageResource(R.drawable.regular_biking);
driving.setImageResource(R.drawable.car_icon);
transit.setImageResource(R.drawable.transit_icon);
}
});
biking.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
travel_mode = "biking";
walking.setImageResource(R.drawable.walking);
biking.setImageResource(R.drawable.regular_biking_sel);
driving.setImageResource(R.drawable.car_icon);
transit.setImageResource(R.drawable.transit_icon);
}
});
Before I've added this piece of code, everything worked correctly.
And here is AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>

</application>
Any ideas?
Thanks.
Please post more code and there is nothing to do with manifest here post layout xml and activity code where you have defined walking and biking findViews().
Just check it out that you have defined findViewsById of both walking and biking before you are calling setOnClickListener method.
Does your application still compile successfully after deleting the two modules?
If it doesn't compile, look for the lines in your classes or xml files which have yellow or red exclamation marks. That should alert you to where the problem is coming from.
You should also take a good look at line 64 in your *welcome.java class.
I have created a sample app called NoteApp, that can save data to Parse. I have created the app in Parse as per the image below, and have created the app..which is still in progress.
I have created the object"testObject", I have matched the ID, and imported data(Ctrl+Shift+O)but when I try to run the app, and check the Parse dashboard, I can't see the object being created. I have tried this so many times, I don't know where the problem is. I just can't link my android app in eclipse with the Parse.com. the app can't create the object, hence I can't save data.
Here is the Application code, and the manifest file, and the image of the Parse.com Dashboard.
NoteApplication.java
package com.echessa.noteapp;![enter image description here][1]
import android.app.Application;
import com.parse.Parse;
import com.parse.ParseObject;
public class NoteApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
Parse.initialize(NoteApplication.this, "XXXXXXXXXXXXXXXX","XXXXXXXXXXXXXXXXXX");
ParseObject testObject = new ParseObject("TestObject");
testObject.put("foo", "bar");
testObject.saveInBackground();
}
}

I have made my Android app, & for minimizing the apk size, I want to use proguard.

Currently there is no code in my project.properties.txt. Please tell me what should I code in project.properties.txt to that the size of my app will be minimized ?
Thanks in advance !
With eclipse i dont think you have to do anything special for the 4 jars you mention that will be locate in the ./libs folder and should get handled automatic by eclipse build.
I dont think with this specific list that you need to alter 'project.properties' in any way.
In proguard config you need the std. treatment for jars, external interfaces...
-keep class android.support.v13.** { *; }
-keep class android.support.v7.** { *; }
-keep class android.support.v4.** { *; }
-libraryjars ...
