You don't need to add the name of your database on your manifest file. You can add database name on strings.xml and just use that string where your database will be created.

Android application crashing, manifest issue

Heloo! I am creating an application in Android. I have declared all my activities in Android manifest, including the main one, and when i start it, it says that the activity i have selected as launcher does not exist:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.boacterapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="18" />
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="22" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="MainPage"
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:label="title_firskljt_activity">
</activity>
<activity
android:name="RecentSightingsPage"
android:label="title_first_activity">
</activity>
</application>
</manifest>
I have been stuck here for a while, so i'm kindly asking that you could help me identity if i have a problem in my manifest. Thank you in advance!

Make sure MainPage activity is in package "com.example.boacterapp".
Another option: replace short name:
android:theme="#style/AppTheme" >
<activity
android:name="MainPage" <----------------- short
android:label="#string/app_name" >
<intent-filter>
With long name that makes up the full class name of your activity:
android:theme="#style/AppTheme" >
<activity
android:name="com.bla.bla.MainPage" <------------- long
android:label="#string/app_name" >
<intent-filter>

Add "." (dot) before MainPage
as
android:name=".MainPage"
Same for others,so rewrite your manifest as
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.boacterapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="18" />
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="22" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainPage"
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=".AboutPage"
android:label="title_firskljt_activity">
</activity>
<activity
android:name=".RecentSightingsPage"
android:label="title_first_activity">
</activity>
</application>
</manifest>

<activity android:name="MainPage"
should be:
<activity android:name=".MainPage"
assuming that your MainPage activity is in the package com.example.boacterapp. If not, you need to provide the fully-qualified name of the MainPage app.

Activity name should have dot prefix, change activity name to .MainPage. Make sure it is inside com.example.boacterapp package

Android Manifest doesn't find <meta-data>

I'm trying to configure my app to program Chromecast featured button.
I'm reading all chromecast SDK and it says that i have to install Google Play Services.
I linked the library to my project, at the same workspace. I did it well because I have a new Android Dependencies library called google_play_services.jar
When I reach this point, I want to test if googlePlayServices are available, so I want to use:
GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
and print a Log with the result.
But the problem appeared here. When I run my app, it says that is not in my Android Manifest.
My Android Manifest has these lines already:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.chromecastAPP"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.INTERNET"/>
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.chromecastAPP.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>
</application>
</manifest>
Any different solution?
Thank you

Meta-data must be in application tags.
"Edit your application's AndroidManifest.xml file, and add the following declaration within the <application> element. This embeds the version of Google Play services that the app was compiled with." Look this link.
Try this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.chromecastAPP"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.chromecastAPP.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>
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</application>
</manifest>

I also Faced this problem. I just updated my SDK Google Play Service with its update Version and it worked for me...
Try it may be it works for you also..

Android: Access Content Provider from another application

I tried searching stackoverflow.com and tried every answer but none of them work.
I have a content provider and it was working when the user of the content provider is in the same application. However, I have Permission Denial error when accessing from another application.
LogCat

Please advise how to declare the permission.
Thanks

If I had to guess, you installed the consumer app before the provider app, which will not work as you have it written.
If you put the <permission> elements in both apps, then the install order will not matter.
Also, you cannot put android:readPermission and android:writePermission on <application>, as you have in your consumer manifest. Simply delete those.
