custom android.app.Application not firing onCreate event

Question

I\'m deriving a custom application from android.app.Application and I can\'t get its onCreate event being fired. Here\'s the implementation

import android.ap         


        

Answer 1

Don't construct it, get it from Context.

For example from Activity:

MyApplication ctrl = (MyApplication)getApplicationContext();

More info: Context.getApplicationContext()

Documentation says that onCreate() is

Called when the application is starting, before any other application objects have been created

Answer 2

I had this issue and found that in my case that the whole issue was phone side. I rebooted the phone and that fixed the issue.

Answer 3

You don't actually create instances of your Activities with the newoperator. Instead you start an Intent like this:

Intent start = new Intent(context, Classname.class);
context.startActivity(start);

When creating an object with the new operator, then onCreate never will be called.

[EDIT] When creating Applications with the new operator onCreate won't be called either[/EDIT]

[EDIT2] You could create a static method that returns the application like this:

public static MyApplication getApp() {
    return mInstance;
}

Answer 4

As Balaji Mentioned if your still facing issue even after mentioning class name under application tag

<application
    android:name="MyApplication"
    android:debuggable="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"> </application>

Then try this:

Try and disabling Instant Run and then clean project and Rebuild it and then run again. It worked for me. Thanks.

Answer 5

Very simple

In your AndroidManifest.xml, within the application tag enter the name of your Application sub-class with it's path under the android:name attribute.

Example:

<application
...
android:name=".models.custom.BaseApplication"
...
> ... </application>

Answer 6

Add following in your AndroidManifest.xml

<application
    android:name="MyApplication"
    android:debuggable="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name">
</application>

then your onCreate() will get fired.
