When they tell me to add default activity class name, should I write com.example.milanovic.hellou.MainActivity or MainActivity or .MainActivity.
com.example.milanovic.hellou is the name of the package I'm using.
<activity android:name=".MainActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
From my understanding, since you specify your package in the AndroidManifest.xml file, the MainActivity's package should be specified relatively to that. For example, if you package is com.example.app and your activity is com.example.app.Activity, then you can type it as .Activity(without dot is also fine), but if it is different, then full package as totally.different.package.Activity, if it is subpackage, try: .subpackage.name.Activity
Finally in your case it is:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.milanovic.hellou">
...
<application ...>
<activity android:name=".MainActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

You are assigning unknown property for application tag, launchMode in android is for Activities. Activities launch and visible to user but Application launch only once when you start your App. You can say Application is a start point in Android App.
Assign a launchMode into Activity not in application tag.
Basically we could assign a launchMode directly as an attribute of <activity> tag inside AndroidManifest.xml file list this:
<activity
android:name=".SingleTaskActivity"
android:label="singleTask launchMode"
android:launchMode="singleTask">
So I have very weird problem with android app that I developed that I really do not understand how to address.
Description of the problem: When I run the app in my emulator(and many other emulators) the app works perfectly, but when I list it on Google Play and some user download the app, it automatically crashes. so I just wonder if my androidmainfest is properly written.

You have posted only your manifest and not the logs. My guesses based on that is the problem may be within your package declaration, rest everything seems fine.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.app".....
The package should be unique and its like what we call package in java world. You have declared it as com.app whereas your app is using com.example.... package. Also com.app maybe used by other app.The package name defines your application's identity.
Once you publish your application, you cannot change the package name. As the package name defines your application's identity, so if you change it, then it is considered to be a different application and users of the previous version cannot update to the new version. So you may have to upload another app with different package name.
Try getting logs(use crashlytics) for your crash and we can look into it for the root cause.
Problem: I'm developing content display app. Now I want to enable GCM push notification app, for that I downloaded a sample project from
http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/
The sample project is working fine and notification are coming as expected.
Now I copy pasted the following files to my project
1. manifest file
2. xml file
3. values file
4. MainActivity file
I changed the Packagename that I need from the pervious code that I copied but still it is not working. Please guide me which line i should change the packagename of project , where I should use class packagename and in where i should use the project packagename.
It is giving me error because the package name and sub package name are same.
Code:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<!-- Register Activity -->
<activity
android:name="com.androidhive.pushnotifications.RegisterActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Main Activity -->
<activity
android:name="com.androidhive.pushnotifications.MainActivity"
android:configChanges="orientation|keyboardHidden"
android:label="#string/app_name" >
</activity>
<receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<!-- Receives the actual messages. -->
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<!-- Receives the registration id. -->
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.androidhive.pushnotifications" />
</intent-filter>
</receiver>
<service android:name="com.androidhive.pushnotifications.GCMIntentService" />
</application>
being a newbie in android development, I'm not able to figure out which is the main package name in this code.
Any suggestion would be great!. thanks in advance
We add it like this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mymain.package"
android:versionCode="1"
android:versionName="1.0" >
Sarthak Mittal is right, but you also need to change your manifest for main activity:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mymain.package"
android:versionCode="1"
android:versionName="1.0" >
<activity
android:name="com.androidhive.pushnotifications.MainActivity"
android:configChanges="orientation|keyboardHidden"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I am having a bit of an issue here, my code seems right, but its not doing what I am expecting it too.
I have an app and I would like to run when the device boots up. But when the device boots up, it application does not run, which is what I am expecting.
First in my Manifest, I added the uses-permission for RECEIVE_BOOT_COMPLETED:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Then also in my Manifest I added a receiver and activity inside the application:
<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="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name=".BootReceiver"
android:enabled="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
<activity
android:name=".BootReceiver"
android:label="#string/title_activity_boot_receiver" >
</activity>
</application>
And then I created a BootReceiver Activity that looks like this:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class BootReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
When I install the app, boot the device, the app does not run right when the device boots up.
I do not understand what I am doing wrong here. Is my code wrong? Anyone got any ideas?
BootReceiver is not your Activity it is class which extends broadcast receiver.
update your manifest, this will be enough
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<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>
<receiver
android:name=".BootReceiver"
android:enabled="true"
>
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
/>
</intent-filter>
</receiver>
</application>
Step #1: Get rid of <activity android:name=".BootReceiver" ..., as you do not have an Activity named BootReceiver.
Step #2: Get rid of <category android:name="android.intent.category.DEFAULT" />, as categories are not usually used on broadcasts, and definitely is not used here.
Step #3: Get rid of android:permission="android.permission.RECEIVE_BOOT_COMPLETED", as that indicates that the sender of the broadcast must hold that permission, which may not be true.
You will be looking to have a manifest that looks more like:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.commonsware.android.sysevents.boot"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk
android:minSdkVersion="7"
android:targetSdkVersion="11"/>
<supports-screens
android:largeScreens="false"
android:normalScreens="true"
android:smallScreens="false"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name">
<receiver android:name=".OnBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
<activity
android:name="BootstrapActivity"
android:theme="#android:style/Theme.NoDisplay">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
</manifest>
(from this sample app)
That's strange 'cause all you mentioned with Manifest and code seems good...
So do you mean no MainActivity is running after Boot?
BTW I used this in my Manifest and works fine:
<receiver
android:name="com.example.BootMeUp"
android:enabled="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
Try this: This code works for me....
<receiver
android:name="your.package.name.BootReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
My application installs, atleast according to Eclipse, as it should. Then it stops with the following in the console:
[2011-10-17 14:10:58 - AppName] Uploading AppName.apk onto device 'emulator-5554'
[2011-10-17 14:11:07 - AppName] Installing AppName.apk...
[2011-10-17 14:11:23 - AppName] Success!
[2011-10-17 14:11:24 - AppName] \AppName\bin\AppName.apk installed on device
[2011-10-17 14:11:24 - AppName] Done!
When i click the launcher icon i get a toast saying:
"Application is not installed on your phone"
This is my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</intent-filter>
you have put the above code out of activity tag.Put it inside activity tag.
change this
<activity android:name="com.qualifiedpath.appname.AppTitleScreenActivity"
android:label="label"
android:screenOrientation="portrait"
android:noHistory="false"
android:launchMode="standard">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
you need to place intent filter inside the activity tag
use this code
<activity
android:name="com.qualifiedpath.appname.AppTitleScreenActivity"
android:label="label"
android:screenOrientation="portrait"
android:noHistory="false"
android:launchMode="standard">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
