I created a application to launch other with this code:
Intent i;
PackageManager manager = getPackageManager();
try {
i = manager.getLaunchIntentForPackage("com.example");
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
if (i == null)
throw new PackageManager.NameNotFoundException();
startActivity(i);
} catch (PackageManager.NameNotFoundException e)
{
This code works correctly (can start application) for Facebook, Google Maps, another application created by me (com.example).
My test aplication (com.example) can resume, but always to root activity.
This application has two activities. First activity (Main Launcher), and a second activity. When I navigate to second activity (Main -> second), and execute application Launcher (above code), my application test run to foreground, but always show the first activity and destroy the second activity.
The test application (com.example) manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Facebook and Google Maps resume the last visible activity (not launcher activity).
Properties are well defined in above manifest?
The behavior of Facebook and Google Maps, is standard, or results of the code of activities, etc?
Thanks in advance for your help.
Problem solved, with the solution below.
Now I can start my application, if it is closed or resume (resume in any activity).
The code that starts the application is (Launcher):
Intent i;
PackageManager manager = getPackageManager();
try
{
i.addFlags(0);
i.setPackage(null);
if (i == null)
throw new PackageManager.NameNotFoundException();
startActivity(i);
}
catch (PackageManager.NameNotFoundException e)
{
}
My application that starts, has the following manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0" >

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:label="#string/app_name"
android:name=".Main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Screen2"
android:label="#string/screen2Title"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout"
android:windowSoftInputMode="adjustResize"
android:launchMode="singleTask" >
</activity>
<activity android:name=".Screen3"
android:label="#string/screen3Title"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout"
android:windowSoftInputMode="adjustResize"
android:launchMode="singleTask" >
</activity>
</application>
</manifest>
Now the application is resumed to any activity, without ever navigate to the root activity.

i have actually found a solution, this problem persists only in phones which have android marshmallow, this update has a security issue, user has to manually allow what permissions the app will have.go to settings->apps->your app->permissions->enable required permissions. your welcome
Is this permission in your manifest.xml?
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
I got this error message when running from command line:

I've tried ant clean, rebuild project and so on.
When clicking on the menu button to build the project, i got BUILD SUCCESSFUL.
hoping for some help. I am receiving an error:
04-13 15:01:45.336: E/AndroidRuntime(11065):
android.content.ActivityNotFoundException:
Unable to find explicit activity class {com.domakecreatedesign.getfit/com.domakecreatedesign.runtracker.RunActivity};
have you declared this activity in your AndroidManifest.xml?
...
However I have declared said class RunActivity in the manifest. However, I notice that the path is not correct, it should be calling com.domakecreatedesign.runtracker.RunActivity, however as you can see from above, it is making a call for: com.domakecreatedesign.getfit/com.domakecreatedesign.runtracker.RunActivity...
I have no idea why this is.

And the calling method is:
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// the id argument will be the Run ID; CursorAdapter gives us this for free
Intent i = new Intent(getActivity(), com.domakecreatedesign.runtracker.RunActivity.class);
i.putExtra(com.domakecreatedesign.runtracker.RunActivity.EXTRA_RUN_ID, id);
startActivity(i);
}
Also worth noting, the application is contained within two packages
com.domakecreatedesign.getfit
com.domakecreatedesign.runtracker
Does this need to be declared somehow in the manifest?
Any help would be very much appreciated.
Many thanks
try ActivityName.this instead of getActivity()
Intent i = new Intent(getActivity(), com.domakecreatedesign.runtracker.RunActivity.class);
something like this,
Intent i = new Intent(AcitivityName.this, com.domakecreatedesign.runtracker.RunActivity.class);
Try this..
Intent i = new Intent();
i.setComponent(new ComponentName("com.domakecreatedesign.getfit", "com.domakecreatedesign.runtracker.RunActivity"));
startActivity(i);

Unable to load maps into an android(samsung) phone. It just displays grid cells without loading the maps. This is my first time developing an android application. Could you please help in what else needs to be done apart from the below steps.
Downloaded the android version(eclipse).
Installed all the required API's for google maps.
Set the manifest file.

If you are using google map v2 then first create(check) api key.
You have to add google-play-services library.

android:targetSdkVersion="17" />

android:protectionLevel="signature" />

References:
link link2
Please refer link and change xml,java and manifext.xml
If you find any trouble then let me know.
In AndroidManifest.xml, add the following element as a child of the element, by inserting it just before the closing tag :
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="your_api_key"/>
You are missing
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>
Few permissions are repeated remove them
Go through the steps in the link. I doubt you have followed the steps from the below link.
https://developers.google.com/maps/documentation/android/start.
You can also follow the tutorial in the link below
http://www.youtube.com/watch?v=awX5T-EwLPc
Edit :
You also require
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
You can also get rid of
<permission
android:name="com.example.package.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
For more information read
