I know there were some questions similar to this... but they didnt clear my issue.
I want to call an activity using setAction but i am getting run time exception..
"No Activity found to handle Intent"...
here is my manifest file
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Main2Activity">
<intent-filter>
<action android:name="com.example.prem.intents.Main2Activity"/>
</intent-filter>
</activity>
here is my MainActivity code...
b4=(Button)findViewById(R.id.btn3);
b4.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String s="com.example.prem.intents.Main2Activity";
Intent i=new Intent();
i.setAction(s);
startActivity(i);
}
});
Could you try code in below in your manifest?
<activity android:name=".Main2Activity">
<intent-filter>
<action android:name="com.example.prem.intents.Main2Activity"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
In Documentation they says:
To receive implicit intents, you must include the CATEGORY_DEFAULT category in the intent filter. The methods startActivity() and startActivityForResult() treat all intents as if they declared the CATEGORY_DEFAULT category. If you do not declare this category in your intent filter, no implicit intents will resolve to your activity.

I have an application, that can be successfully setup as Device Owner on devices up to Android 12 via QR code from JSON below:
{
"android.app.extra.PROVISIONING_DEVICE_ADMIN_COMPONENT_NAME":
"package.CustomDeviceAdminReceiver",
"android.app.extra.PROVISIONING_DEVICE_ADMIN_PACKAGE_CHECKSUM":
"actual_checksum",
"android.app.extra.PROVISIONING_DEVICE_ADMIN_PACKAGE_DOWNLOAD_LOCATION":
"https://Site/APK_Link",
"android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED": true
}
App contains declared receiver:
<receiver
android:name=".deviceadmin.CustomDeviceAdminReceiver"
android:description="#string/app_name"
android:label="#string/app_name"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<meta-data
android:name="android.app.device_admin"
android:resource="#xml/enterprise_device_admin" />
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
<action android:name="android.app.action.PROFILE_PROVISIONING_COMPLETE" />
</intent-filter>
</receiver>
For Android 12 (as described here https://source.android.com/devices/tech/admin/provision) I added 2 activities:
<activity
android:name=".deviceadmin.AdminPolicyComplianceActivity"
android:screenOrientation="portrait"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<intent-filter>
<action android:name="android.app.action.ADMIN_POLICY_COMPLIANCE"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".deviceadmin.ProvisioningModeActivity"
android:screenOrientation="portrait"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<intent-filter>
<action android:name="android.app.action.GET_PROVISIONING_MODE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
1st one:
public class ProvisioningModeActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_provisioning_mode);
Intent intent = getIntent();
int provisioningMode = 1;
List<Integer> allowedProvisioningModes = intent.getIntegerArrayListExtra(DevicePolicyManager.EXTRA_PROVISIONING_ALLOWED_PROVISIONING_MODES);
if (allowedProvisioningModes.contains(DevicePolicyManager.PROVISIONING_MODE_FULLY_MANAGED_DEVICE))
provisioningMode = DevicePolicyManager.PROVISIONING_MODE_FULLY_MANAGED_DEVICE;
else if (allowedProvisioningModes.contains(DevicePolicyManager.PROVISIONING_MODE_MANAGED_PROFILE))
provisioningMode = DevicePolicyManager.PROVISIONING_MODE_MANAGED_PROFILE;
Intent resultIntent = new Intent();
resultIntent.putExtra(DevicePolicyManager.EXTRA_PROVISIONING_MODE, provisioningMode);
setResult(RESULT_OK, resultIntent);
finish();
}
}
and 2nd one (almost empty):
public class AdminPolicyComplianceActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_admin_policy_compliance);
setResult(RESULT_OK);
finish();
}
}
but I got error while enrollment: "Can't setup device. Can't use the admin app. It's missing components or corrupted".
Can somebody find that I missed please?
From Android 12 we are supposed to have components exported safely. Since your activities ProvisioningModeActivity and AdminPolicyComplianceActivity uses intent filter, we have to set the exported flag.
<activity
android:name=".deviceadmin.AdminPolicyComplianceActivity"
android:screenOrientation="portrait"
android:permission="android.permission.BIND_DEVICE_ADMIN"
android:exported="true">
<intent-filter>
<action
android:name="android.app.action.ADMIN_POLICY_COMPLIANCE"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".deviceadmin.ProvisioningModeActivity"
android:screenOrientation="portrait"
android:permission="android.permission.BIND_DEVICE_ADMIN"
android:exported="true">
<intent-filter>
<action android:name="android.app.action.GET_PROVISIONING_MODE"
/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
This way firmware will be able to recognize the activity and launch it.
Also, regarding android:testOnly="false", this flag must be false if you are going to do QR code provisioning. If its true then, you will be able to remove admin via android settings.
#faz the reason this code doesn't work on Android 11 and below is because the ProvisioningModeActivity intent is not fired with an extra integer array of DevicePolicyManager.EXTRA_PROVISIONING_ALLOWED_PROVISIONING_MODES. To overcome this add a null check to the allowedProvisioningModes
I have MainAcitivty on which I am adding multiple intent-filters, with a purpose to open the MainActivity.
But the problem is that onNewIntent() is called but intent.action is always main, even when it should be VIEW_RICH_PUSH_MESSAGE. If I remove the second intent filter and add that to another new Activity, it will work for that Activity.
What I want is to define multiple intent filters for one Activity but I couldn't figure out the problem.
My manifest is defined as follows:
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main"
android:screenOrientation="portrait"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<action android:name="com.urbanairship.VIEW_RICH_PUSH_MESSAGE" />
<data android:scheme="message"/>
<category android:name="android.intent.category.BROWSABLE"/>
</intent-filter>
</activity>
Any help is appreciated.
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();
}
I am trying to use Implicit intent to launch an activity within the same application and for an activity of another application(my other application, not the native one), but couldn't succeed in any of the cases.
Here is my sample code for the first part (i.e. to launch an activity within the same application):
Inside Activity TESTActivity
Intent intent = new Intent();
intent.setAction("com.myapp.game.myimplicit_action");
startActivity(intent);
and here is my manifest file declaration for some activity say 'ImplicitActivity' with the same action:
<activity
android:name=".TESTActivity"
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=".ImplicitActivity">
<intent-filter>
<action android:name="com.myapp.test.myimplicit_action" />
</intent-filter>
</activity>
Both the activities TESTActivity and ImplicitActivity are in the same application under same package. Still my ImplicitActivity activity is not getting called.
I have figured out the problem. Posting the answer for the others facing the same problem.
We need to add Default Category in order to make Implicit intents work. So here is the correct manifest entry for the same activity :
<activity
android:name=".TESTActivity"
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=".ImplicitActivity">
<intent-filter>
<action android:name="com.myapp.test.myimplicit_action" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
I keep getting "ActivityNotFoundException: Unable to find explicit activity class ... " when using Eclipse's emulator to call the activity of another application from an application. Perhaps the problem maybe related to I am not able to download to/find both applications at the same time when I click on "Manage Applications" in Settings. This is the first project I need to call the activity of another application. But I am not sure the code is correct either. Please help me determine if there are errors in the code snippets I present below. It is hinted that I can set the action field of the intent to achieve the objective but have not found learning material for this. I learned about using the setComponent method in the calling app and to add android:export to the called activity's AndroidManifest.xml. Thanks in advance!
Calling app's relevant source code:
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.MyPackage", om.MyPackage.Activity1));
startActivity(intent);
Calling app's relevant AndroidManifest.xml :
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".MainActivity"
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=".Activity1">
<intent-filter>
<action android:name="com.MyPackage.Activity1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
Relevant code of AndroidManifest.xml of the activity of another application
<activity android:name=".Activity1" android:exported = "true">
<intent-filter>
<action android:name="com.MyPackage.Activity1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Firstly point out that you're trying to start Activity in Application2 from Activity in Application1
You have to give them separate namespaces
both applications now have com.MyPackage.* prefix
OR use names Activity1 and Activity2
So you will have
com.MyPackage1.Activity1
// and
com.MyPackage2.Activity1
Then you can use this code, to start Activity1 in MyPackage2 from MyPackage1.
// in file com.MyPackage1.Activity1
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.MyPackage2", "com.MyPackage2.Activity1"));
startActivity(intent);
And your AndroidManifest.xml files should look like this:
first
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name="com.MyPackage1.Activity1"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
second
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name="com.MyPackage2.Activity1"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
