I'm trying to learn Java and need some help with AndroidManifest.xml
My little hello world project is working code-wise, but I'm confused with making changes to the manifest. Specifically, in the code above package name is "com.android" and in data/app my app shows up as com.android-1.apk. When I try to change it to something like com.jocala or com.jocala.hba1c I get package R does not exist errors through my compile, which fails.
What changes do I need to make? Anything else here that is glaringly bad?
I am working using Ant, VI and the Linux console, no Eclipse.
You should change the package of the java code, let it in accordance with the package which you defined in the manifest file.
The manifest holds meta-data corresponding to your android application. Hence, if you needs changes in the package name, make the changes in the java files, change the package name there, there is no sense making a change here. The only changes that are majorly done in the manifest are activity related(for beginners). Have a read here.

I have this code and I was told that for Android 11 I need to add the queries tag in manifest:
final PackageManager pm = getPackageManager();
Intent main = new Intent(Intent.ACTION_MAIN, null);
main.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> packages = pm.queryIntentActivities(main, 0); //get a list of installed apps.
I was told it should be this:
<queries>
<intent>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent>
</queries>
Problem is I cannot add the <category> tag. Android Studio says that the element is not allowed there. I can only add the <action> and <data> tags inside <intent>. And it seems other people on SO have this problem too. It's strange because Android's own documentation instructs us to use the <category> tag there.
The <queries> section is introduced in API 30, so be sure you use it only if you target such version upward.
It is indeed needed when, for instance, you want to launch some other apps from yours, knowing only their package name. Otherwise, using the package manager will return you some null when using functions like packageManager.getLaunchIntentForPackage("com.yyy"). You can find more information here: Package visibility in Android 11
In your case, you can just write the section like this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xxx">
...
<queries>
<intent>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent>
</queries>
...
</manifest>
total noob with lots of issues with Android Studio.
Default Activity error
Invalid java package name
Getting a Default Activity error on any app or new project I run - below is an example of the AndroidManifest.xml
"Error running 'app': Default Activity not found"
I have checked more than 100 times I am using the right package names and that my activity is declared in the android manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.coleary.change;">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name="com.example.coleary.change.MainActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:label="#string/TicTacToe"
android:theme="#style/AppTheme"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
The package name is the same in the java code:
package com.example.coleary.change;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
// use tictactoe code in our code for a new game
private TicTacToeGame mGame;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(com.example.coleary.change.R.layout.activity_main);
//this activity(game) is a context within a main activity
mGame= new TicTacToeGame(this);
}
}
When I run the project I get the following error also:
Package 'com.example.coleary.change;' from AndroidManifest.xml is not a valid Java package name as 'change;' is not a valid Java identifier.
I have changed the package name through Refactoring to 5 different names to no avail.
I have spent over 15 hours hours trying to troubleshoot these issues and because I have the same issue on multiple projects / packages and apps I am completely stuck - any help really appreciated!
Remove the semi-colon after change in your AndroidManifest. Package names can't contain semi-colons.
Before labeling this as a duplicate:
I've read at least 15 similar threads and each and every one is either using the old Parse code (the now deprecated setDefaultPushCallback) or the problem was a result of calling Parse.initialize(...) in an activity and not in the Application class. But this is not applicable to my case. The official example (which I'm using) is evidently doing it right, so the code is already in the Application class.
I've downloaded the Push Starter example from Parse's official guides and tried it out on an emulator. I receive pushes only while the app is running. The moment's it's closed (removed from the "recent apps" list, not force killed), I no longer get pushes. Which makes the entire feature rather useless... I tried with and without GCM, the behavior is the same.
Any clues what could possible be wrong? All classes are the stock example ones, nothing overridden or added by me (except for the id/key and the ParsePush.subscribeInBackground call which I copied from the guide). Weirdly enough, the example code did not contain ParsePush.subscribeInBackground and the QuickStart does not mention it. It even gives a Test button that supposedly sends a push which I never receive, with or without subscribeInBackground. The only way I've been able to get a push so far was with subscribeInBackground and sending a push manually though the web console, and only so if the app is running. The web console also keeps telling there's 2 registered devices... which is untrue.

Just to clarify why you are seeing this behaviour, Parse has two different ways for delivering push notifications:
"Parse way": the Parse SDK has a component running in your app, which keeps a connection to the Parse backend servers. This will only work when your app is actually running, because killing it breaks the connection with the Parse backend.
GCM "Google" push notifications: This works via Google Play Services, an app which is always running in the background and that can start your app when needed. This will always work, unless you force stop the application.
In your case you are there is a package name conflict: com.parse.starter is the package name that was actually included in the example. This causes GCM not to work, because it already knows the package under a different signature. Changing your package name to something unique like com.parse.kaqqao should solve the trick.
There are a few reasons for this:
There are two BroadcastReceiver viz the "com.parse.ParsePushBroadcastReceiver" and "com.parse.GcmBroadcastReceiver". I believe that the first receiver is getting prioritized over the GCMBroadcastReceiver and thus the behavior is not affected by removing or keeping this receiver. It could also be due to action "com.parse.push.intent.RECEIVE", which might be handling the push messages RECEIVE action. If both the receiver perform the same task of parsing the Push message (starting the same service in background), then include the intent-filter inside one receiver and let it handle all kinds of push messages. Since GCMBroadcastReceiver holds the C2DM permission.
Try changing the order of the two broadcast receiver tags in the manifest. (Keep GCMBroadcastReceiver before the ParsePushBroadcastReceiver)
It could be due to android:exported="false", maybe it prevents the Receiver from listening to the push messages sent by server. Try changing to true.
So essentially I've been making a game using libgdx and just recently I started to try and add Google Play Game Services and So I tried my hand at it and it seems as though I have completely messed up my .xml file I've tried looking at questions such as How do I resolve this Java Class not found exception? and NoClassDefFoundError - Eclipse and Android, but to no avail.
Here is the runtime error I am recieving.
02-19 19:25:17.772: E/AndroidRuntime(25746): FATAL EXCEPTION: main

The class Name is MainActivity.Java and it is in the src file. I understand that this is done because of one of two things: My .class file, or the .xml file. So here is also my .xml file just in case what I have done wrong is there and not in fact in any .class file.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.coppercow.minerman"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
However I've messed around with this xml file quite a lot and so I do not believe it is in here and that My whole problem has to be in some .class file somewhere, but I don't even understand how to access those from eclipse from going off of other questions asked here on StackOverflow.
Try this:
Go to Project/Properties/Java Build Path/Order and Export -- Make sure there's a check in front of Android Dependencies and the support library, if you use it.Mark all checkboxes and Click on Apply and clean the project.
Hope this helps.

I am a bit stuck... any ideas? O_o
Thank you for your help in advance.
Look at this post. Probably you didn't build the project before packaging it. You'll only want to create the AIR package to redistribute your application.
I also have this problem. Then I reboot win7. It works well after that.
