Apps startActivity didn't work

[RaoulH]

Hello,

in my app, i use the method startActivity to launch a new activity.
The code that i use:

startActivity(new Intent(this, SigninActivity.class));

but when the startActivity is called, the new activity wasn't launch, it relaunch the current activity.
In LogCat, i found this:

06-29 17:17:27.887 22615-22615/com.lekonquer.xxx.xxxxW/ActivityThread: handleWindowVisibility: no activity for token android.os.BinderProxy@84263c1

Please could you have an idea of the issue?

Thanks

That's a strange problem.
But we really need to see a bit more code around that line, to establish the context.
Seeing the code for SigninActivity class would be useful.
The logcat content doesn't really shed any light on the problem.

Another thing you could try is running your app in debug mode and setting a break point in onCreate()

Hello,
@LV426, thank you for your reply. It's very strange,
I will try to run in debug mode.
This is the entire code:

package com.lekonquer.raoul.geoconnect;

    }

    }
}

Did your app crashed ?

 

[Cao Van Thanh]

Did you define your activity in manifest.xml?

 

[RaoulH]

Did you define your activity in manifest.xml?

Yes i defined it:

.........
<activity
            android:name=".SigninActivity"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen" />
......

No

 

[wseng92]

Are you sure it running the if block?

Are you sure it running the if block?

There's only one way to find out... Breakpoint it!

Hello,
finally, after many hours spent to understand what's wrong. I finally found the mistake. When i called

setContentView(R.layout.activity_xxxxxxx);

i used the same layout for the 2 activities and that it is not good.
When i changed that it is ok.
Many thanks for your replies

In my case, This occurred when i was trying to pass a really long JSON string through intent extras. From what I can infer , passing a really large value through the extra bundle might lead to memory issues when starting the new intent. Try using shared preferences or serializable objects to share large stuff between activities

Hope that helped!
