I just want to code for splashscreen. for that I used intent but I am getting error that instrumention source not found. I have two files splashscreen.java and myapps.java where I have use threading concept and called anothe activity as
finally
{
finish();
startActivity(new Intent("com.example.MyApps"));
stop();
}
# startAcitivy I am getting axception please guide me do I have to modify androidmanifest file? if yes please provide me syntax for that.
If you're starting a new Activity with intent, I prefer using it like:
Intent intent = new Intent(MyClass.this, MyApps.class);
startActivity(intent);
and have proper entry on your manifest for your MyApps class like:
<application>
.......
.....
<activity android:name="com.example.MyApps" />
........
</application>
Add
<activity android:name="com.example.MyApps"></activity>
in your manifest.

android.content.ActivityNotFoundException: Unable to find explicit activity class {com.myapp.videomodule/com.myapp.videomodule.VideoCallActivity}; have you declared this activity in your AndroidManifest.xml?
My app package is com.myapp.doctors
module package is com.myapp.videomodule
if(splitInstallManager.getInstalledModules().contains("videomodule")){
Intent intent = new Intent();
intent.setClassName("com.myapp.videomodule", "com.myapp.videomodule.VideoCallActivity");
startActivity(intent);
}
I have declared it in the manifest the thing is I am trying dymanic module delivery, so that videoactivity is in other module
It seems that dynamic feature modules are declared in base app package. (as you can verify using Merged Manifest feature on your module Manifest.xml
I suggest the following modification:
if(splitInstallManager.getInstalledModules().contains("videomodule")){
Intent intent = new Intent();
intent.setClassName(getPackageName(), "com.myapp.videomodule.VideoCallActivity");
startActivity(intent);
}
Go to manifests > AndroidManifest.xml > check if com.myapp.videomodule.VideoCallActivity is declared there, if not, put it like:
<manifest>
....
<application
...>
...
<activity
android:name="com.myapp.videomodule.VideoCallActivity"
android:label="#string/title_videocallactivity" your activity title
android:theme="#style/AppTheme.NoActionBar" />
...
</application>
</manifest>
Try starting the intent like this:
Intent intent = new Intent(this, VideoCallActivity.class);
startActivity(intent)
I have a ADT app, myadtapp (myapppkg), uses an Android Lib, myadtlib (mylibpackage). Inside myadtlib project, I created a custom Activity, myjavapkg.MyActivity, and declare the Activity in MyAdtLib::AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="mylibpackage" ... >
...
<application>
<activity
android:name="myjavapkg.MyActivity"
android:exported="true" />
...
I am surprised the following code doesn't work:
Intent intent = new Intent();
intent.setClassName("mylibpackage", MyActivity.class.getName());
startActivity(intent);
The error is:
ActivityNotFoundException: Unable to find explicit activity class {mylibpackage/myjavapkg.MyActivity}; have you declared this activity in your AndroidManifest.xml?
If I move MyActivity declartion to the myadtapp manifest file, it would work, but I don't want to. What is wrong with the above using an MyActivity in an my Android lib?
This should work:
Intent intent = new Intent(this, MyActivity.class);
startActivity(intent);
I have been trying to invoke another activity from the mainactivity class with the code:
startActivity(new Intent("intent filter name here"));
However when I debug the application when it gets to this line I get a source not found message in the class file editor that says the source attachment does not contain the source for the file ClassLoader.class. There is an option to change the attached source "android.jar" but there is only one such file under the_targetAPI folder. How can i fix this?
Try this:
Intent intent = new Intent(this, secondactivity.class);
startActivity(intent);
And don't forget to add it to manifest.xml.
By upper error also try to clean or rebuild the project.
Intent from one activity to another:
Intent ii=new Intent(Firstactivity.this,Secondactivity.class);
startActivity(ii);
Import tis one :
import android.content.Intent;
Add both classes in your Manifest.xml:
<activity
android:name="com.example.task.secondActivity"
android:label="#string/app_name" />
Try this one , its may work. check the manfest.xml ,
Source not found ClassLoader.class when invoking an activity from main
this may be the reason. check it out :)
Happy coding :)
In my app, I have to use Intent.setClassName or setComponent to start an activity in another package. There is no problem when I use Intent.setClass like
Intent intent = new Intent(getApplicationContext(), org.iustb.knowledebase.animation.transparent.MainTransparentActivity.class);
The suggestions to solve this problem on the web is that adding or android:exported="true" to the target activity in the AndroidManifest, but it doesn't work.
Is there anybody can help me?
i wrote the below code:
Intent intent = new Intent();
intent.setClassName(cursor.getString(pIndex), cursor.getString(cIndex));
startActivity(intent);
manifest file settings of the target activity:
<activity android:name="org.iustb.knowledebase.animation.transparent.MainTransparentActivity"
android:exported="true"></activity>
Did you make sure the values that the cursor returns the are correct ones?
The first parameter of the setClassName() should be the application package name, not the package where the Activity beings started is.
Assume the application package is: com.testandroid, but you want to start the other activity from the com.testandroid.other package, then your code should look like this:
intent.setClassName("com.testandroid", "com.testandroid.other.OtherActivity");
in my case it was a conflict between package=com.example.myApplication in the AndroidManifest.xml file under the <manifest> tag and applicationId in the build.gradle:app module under the defaultConfig tag. hope it would help.
I have an Android library project that I would like to use from within another Android project.
The library has a Activity declared in its AndroidManifest. When I try the following within the second project:
Intent intent = new Intent(this, ReaderActivity.class);
startActivity(intent);
I get the following exception:
java.lang.RuntimeException: Unable to start activity ComponentInfo{br.com.digitalpages.reader.demo/br.com.digitalpages.reader.demo.ReaderDemoActivity}: android.content.ActivityNotFoundException: Unable to find explicit activity class {br.com.digitalpages.reader.demo/br.com.digitalpages.reader.ReaderActivity}; have you declared this activity in your AndroidManifest.xml?
at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2663)
...
Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {br.com.digitalpages.reader.demo/br.com.digitalpages.reader.ReaderActivity}; have you declared this activity in your AndroidManifest.xml?
at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1404)
at android.app.Instrumentation.execStartActivity(Instrumentation.java:1378)
...
How can I open the Activity from the another project?
EDIT:
By users answers I added the following line into my second project
<uses-library android:name="br.com.digitalpages.reader" android:required="true" />
But it's still doesn't works
I believe you must include the <activity> in your own AndroidManifest.xml -- I don't think it gets picked up from a library. I don't have my reference for that handy.
Update: It's official solution. From the doc:
Declaring library components in the manifest file
In the manifest file of the application project, you must add
declarations of all components that the application will use that are
imported from a library project. For example, you must declare any
<activity>, <service>, <receiver>, <provider>, and so on, as well as
<permission>, <uses-library>, and similar elements.
Declarations should reference the library components by their
fully-qualified package names, where appropriate.
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.setComponent(new ComponentName("packagename//ex-com.hello",
"classname//ex-com.hello.ExampleActivity"));
startActivity(intent);
And make sure in library you have declared the activities. You don't need to declare the library activities in your current project's manifest.
did you add to the manifest?
http://developer.android.com/guide/topics/manifest/uses-library-element.html
This works:
In your library, put your custom Activity:
public class MyLibraryActivity extends ListActivity { ... }
No need to put it into a manifest.
In your calling Android project, create an empty (dummy) wrapper:
public class MyActivity extends MyLibraryActivity { }
and add reference to this class to your manifest:
<activity android:name="my_package.MyActivity" ... />
I am aware that the question is quite old but I think this might help people like me that came up with the same problem.
Using Eclipse, the best way to share code and activities among libraries is probably the one that can be found in the android documentation here:
Managing Projects from Eclipse with ADT
When using an activity inside the library, the activity should be declared only inside the manifest of library.
The activity can be started from the main app like this:
Intent intent = new Intent();
intent.setClassName(this, "com.duna.remotelocklibrary.activities.MainRemoteActivity");
startActivity(intent);
I tried to start the library's activity like the following code, but i warn you: it doesn't work
Intent intent = new Intent();
intent.setClassName("com.duna.remotelocklibrary", "com.duna.remotelocklibrary.activities.MainRemoteActivity");
startActivity(intent);
you should import just the code of the activity ( not the manifest too ) , and then , declare your Activity ( of the library ) , in the manifest of your second project
You don't need to explicitly add activity in your main project's manifest if you have already added the activity in your library's manifest by using the following code when starting library's activity.
For Kotlin
val myIntent = Intent(activityContext, ActivityToLaunch::class.java)
// Needed to set component to remove explicit activity entry in application's manifest
myIntent.component = ComponentName(activityContext, PickerActivity::class.java)
activityContext.startActivity(myIntent, PICKER_REQUEST_CODE)
For Java
Intent myIntent = new Intent(activityContext, PickerActivity.class);
// Needed to set component to remove explicit activity entry in application's manifest
final ComponentName component = new ComponentName(activityContext, PickerActivity.class);
myIntent.setComponent(component);
activityContext.startActivity(myIntent, REQUEST_CODE);
