I have play buttons on custom popups and they are taking me to the wrong activity and im not sure why. The activity its launching is not even in the onclick method.
Button playit = (Button) dialog.findViewById(R.id.playDetourDialog);
playit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
System.out.println("go to pyramid");
Intent i = new Intent(getApplicationContext(), PyramidGamePlay.class);
startActivity(i);
dialog.dismiss();
}
});
manifest:
<?xml version="1.0" encoding="utf-8"?>
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".Main"
android:label="#string/app_name" android:theme="#android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:theme="#android:style/Theme.NoTitleBar" android:name="GamePlayRegular"></activity>
<activity android:theme="#android:style/Theme.NoTitleBar" android:name="WorldSelect"></activity>
<activity android:theme="#android:style/Theme.NoTitleBar" android:name="OptionsPage"></activity>
<activity android:theme="#android:style/Theme.NoTitleBar" android:name="World"></activity>
<activity android:name="GameEndPage" android:theme="#android:style/Theme.NoTitleBar"></activity>
<activity android:theme="#android:style/Theme.NoTitleBar" android:name="PyramidGamePlay"></activity>
</application>
Use like this
<activity android:name="PyramidGameplay">
<intent-filter>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
It's hard to know without more information. Have you defined your activity in your AndroidManifest.xml? What info does logcat print when you tap the playit button?
It would also be good to use the android.util.log package for logging, rather than using System.out.println.

I have a shoppinglist App coded in Android-Studios. My app does have a splash screen. When I install the app, it is installed twice. When I uninstall one, the other one uninstalls too. I tried to delete the first intent filter on splashscreen, but then I did not have a splash screen anymore. I want my splashscreen to be remain. How to solve that? My manifest looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.projects.buylist">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".SplashScreen"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
The app is only one.
You have simply two activities (and then 2 icons) that can work as launcher.
If you don't want, you have to remove this part in one Activity
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<category android:name="android.intent.category.LAUNCHER" /> this is telling android you want the activity to be visible from the app launcher. To solve it, remove the intent-filter from MainActivity.
Delete your main intent in XML and create something like this, which will run splashscreen and then open your MainActivity
public class SplashsScreen extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_screen);
new Handler().postDelayed(new Runnable(){
#Override
public void run() {
Intent mainIntent = new Intent(SplashsScreen.this, MainActivity.class);
SplashsScreen.this.startActivity(mainIntent);
SplashsScreen.this.finish();
}
}, 1500); // 1500 ms = 1.5 s
}
}
I'm trying to start an activity in another package, I already saw a lot of answers on the topic, but the answers I found don't seem to work for me.
Here how I call the other activity:
Intent intent = new Intent();
intent.setClassName("com.packageroot.package2", "com.packageroot.package2.MainActivity");
context.startActivity(intent);
And here my Manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.packageroot" >
<application
<activity
android:name=".package1.MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.packageroot.package2.MainActivity"
android:label="#string/title_activity_main"
android:theme="#style/AppTheme"
android:parentActivityName=".package1.MainActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".package1.MainActivity"/>
</activity>
And I still get this error:
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.packageroot.package2/com.packageroot.package2.MainActivity}; have you declared this activity in your manifest?
What I don't get is that the path indicated is the error is exactly the name of the activity...
Thanks a lot in advance.
You could try adding the package to the build.gradle file under dependencies:
dependencies {
compile 'com.packageroot.package2'
}
change this line:
intent.setClassName("com.packageroot.package2", "com.packageroot.package2.MainActivity");
to
intent.setClassName("com.packageroot", "com.packageroot.package2.MainActivity");
The first parameter is "package name".
http://developer.android.com/reference/android/content/Intent.html#setClassName%28java.lang.String,%20java.lang.String%29
If your intent go through packages,this is what you should do.
In your Manifest
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:exported="true">//got to declare this
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="YOUR ACTION NAME" />
//At least one category,use DEFAULT if you don't have one
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
And in your Activity
Intent intent = new Intent();
intent.setAction(YOUR ACTION NAME);
intent.addCategory(Intent.CATEGORY_DEFAULT);
startActivity(intent);
Best Solution Work for me is controlling the back Button
#Override
public void onBackPressed() {
Intent intent = new Intent(CurrentActivity.this, SecoundActivity.class);
startActivity(intent);
finish();
}
Here's the problem guys, first i tried to run my application with Launch default activity as launch action (Run Configurations --> Android --> Launch action), the logcat kept telling me that it can't find the launcher activity and the application wouldn't even start, problem is i defined my launcher activity in the manifest file, but it's like it's not reading it at all.
So i tried to launch the splash activity by specifically telling it to run it through run configurations, it did launch but during the transition to the next activity it crashed again, the logcat says no activity found to handle intent, which again, I defined the way I did in other applications and worked alright there. Plase help it's a nightmare.
Here's the code for the MainActivity:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Thread timer = new Thread()
{
public void run(){
try{
sleep(6000);
} catch (InterruptedException e){
e.printStackTrace();
} finally {
Intent openStarting = new Intent("totaltrainer.com.WorkoutPlace");
startActivity(openStarting);
}
}
};
timer.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}
And Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="totaltrainer.com"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="totaltrainer.com.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".WorkoutPlace"
android:label="#string/app_name" >
<intent-filter>
<action android:name="totaltrainer.com.WorkoutPlace" />
</intent-filter>
</activity>
<activity
android:name=".WorkoutHome"
android:label="#string/app_name" >
<intent-filter>
<action android:name="totaltrainer.com.WorkoutHome" />
</intent-filter>
</activity>
<activity
android:name=".WorkoutGym"
android:label="#string/app_name" >
<intent-filter>
<action android:name="totaltrainer.com.WorkoutGym" />
</intent-filter>
</activity>
</application>
</manifest>
use "totaltrainer.com.WORKOUTGYM" and so on
and below use this
<category android:name="android.intent.category.DEFAULT" />
Problem 1
logcat kept telling me that it can't find the launcher activity and
the application wouldn't even start
In your Manifest file, change below
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="totaltrainer.com.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
as
<activity android:name="MainActivity">
<!-- This activity is the main entry, should appear in app launcher -->
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
What happens when you define this Action and Category ?
The ACTION_MAIN action indicates this is the main entry point and does not expect any intent data.
The CATEGORY_LAUNCHER category indicates that this activity's icon should be placed in the system's app launcher. If the element does not specify an icon with icon, then the system uses the icon from the element.
These two must be paired together in order for the activity to appear in the app launcher.
Problem 2
the logcat says no activity found to handle intent
Your Manifest declaration seems fine.
In your activity class, change
Intent openStarting = new Intent("totaltrainer.com.WorkoutPlace");
startActivity(openStarting);
as
Intent openStarting = new Intent();
openStarting.setAction("totaltrainer.com.WorkoutPlace");
startActivity(openStarting);
I'm trying to do this tab view example from Android Examples, it works fine but I don't see the text (This is the ArtistsTab) in each tab that is set using the TextView. Not sure what I'm doing wrong.
Below are the main contents of my manifest file
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".HelloTabWidget"
android:theme="#android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ArtistsActivity"></activity>
<activity android:name=".AlbumsActivity" ></activity>
<activity android:name=".SongsActivity"></activity>
</application>
Below is the content of OnCreate() method of the ArtistsActivity class
public void OnCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
TextView textView = new TextView(this);
textView.setText("Artists Tab");
setContentView(textView);
}
Thanks
I would guess your Activity doesn't even get called... try adding the following lines to your manifest file:
<activity android:name=".ArtistsActivity">
<intent-filter>
<action android:name="yourpackage.ArtistsActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Replace "yourpackage" with the name of your package and do the same with the corresponding action name within your AlbumsActivity and SongsActivity.
More information on Intents and Intent Filters
Just started working with android and ran into a small problem. I am have a TabActivity that is loading 3 other Activity classes. This works great. I then have a button on the other Activity classes that I would like to launch a MapActivity. When I do that I keep getting a Force Close.
I googled but I cannot figure out if it is the manifest file or something else. The idea is the tabs are showing location information and you click a button to plot it on the map and get directions.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.location_tab);
...
Button btnMap = (Button) findViewById(R.id.btnLaunchMap);
btnMap.setOnClickListener(mMapListener);
}
private OnClickListener mMapListener = new OnClickListener() {
public void onClick(View v) {
Intent mapIntent = new Intent(getApplicationContext(),LocationMap.class);
startActivity(mapIntent);
}
};
If I launch any other activity it works but not launching the mapactivity. If I take the mapactivity class and put it in a new project it works.
My manifest
<uses-permission android:name="android.permission.INTERNET" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".Splash"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Locations"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar"></activity>
<activity android:name=".LocationNewYork"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
</activity>
<activity android:name=".LocationChicago"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar"></activity>
<activity android:name=".LocationSeattle"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar"></activity>
<activity android:name=".LocationMap"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
</activity>
<uses-library android:name="com.google.android.maps"/>
</application>
thougths?
<action android:name="android.intent.action.MAIN" />
inside of the mapactivity's instance ACTIVITY field in the Manifest file does it.
So if you have a MapActivity named QMap, the following code in the Manifest actually works:
<activity android:name=".QMap"><action android:name="android.intent.action.MAIN" /></activity>
Hope it helped
I had the same problem, wanted to launch map activity from an other activity over onClick-event, the problem was: errors in the MapActivity
If you are using eclipse try to run "debug as" without setting any breakpoints
