I'm new just working with some basic Android codes. My problem is that Android Emulator is not showing any output when I run code. It takes really long and on console it sticks here
[2013-03-31 03:17:55 - Helloworld] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.helloworld/.MainActivity }
and emulator looks like this
I have waited for 5-10 minutes but it does not show output. Please guide me where the problem might be. I downloaded sdk ADT Bundle for Windows and configured it as mentioned in official site.
In Eclipse, try :
Window -> Show View -> Other -> Android/Devices
Select the Emulator from the newly added Devices window, and check back your logcat.
I'd try a little debug, and set a break point on the very first line of code in your app's main activity. Then I'd step thru and see where it breaks.
I've just encountered the similar problem, in my case I forgot to add the activity in AndroidManifest.xml file.
The following is my Manifest file for example ...
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testalarm"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="10" />
<uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.testalarm.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="com.example.testalarm.CheckpointActivity" >
<intent-filter>
<action android:name="com.example.testalarm.CheckpointActivity" />
</intent-filter>
</activity>
</application>
</manifest>
Check if you have all required activities as <activity> under <application>

I have tried converted my android app from eclipse to android studio project and app is working on testing on emulator and my real device but I couldn't find it when trying to exit the app .. After publishing to the store I got the same issue + app is never open .. after installing I just got uninstall only on google play store .. please help :)
this is app url to the store : https://play.google.com/store/apps/details?id=com.linkedtalents.app&hl=en
Here is my manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.linkedtalents.app"
android:versionCode="10"
android:versionName="1.1" >
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/launch123"
android:label="#string/app_name"
android:largeHeap="true" >
<activity
android:name="com.linkedtalents.app.Splash"
android:theme="#style/AppBaseTheme"
android:screenOrientation="portrait"
android:configChanges="locale"

it seems that you are missing the intent filter. at least you didnt post it. can you have a look that you have the MAIN LAUNCHER like here? you need exactly one activity that matches this, if you want to be started from a homescreen.
<activity
android:name="..."
android:label="#string/app_name"
android:theme="#style/AppTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
It was all good yesterday, but right now it won't show up when I run the AVD.
Don't know if it is my AndroidManifest.xml file which is pretty standard.
<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<activity
android:name="com.example.app.Hoved"
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>
This is now fixed all, thank you!
The problem was that I write Android app on Xamarin, so you use flags there instead of declaring the activity in the manifest.
You missing this 2 'lines', it's really important but just past it above (over) < application and it's will work.
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="21" />
This is the most basic question, you should know that before u start programming in visual studio or eclipse. Just watch some tutorials on youtube it will help you. Good Luck.
When I run the project the .apk file get uploaded and installed successfully on the device but AVD unbale to launch. Please help me to solve this issue.
Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.bottleworks.dailymoney.core">
<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
</manifest>
If it gives message "unable to upload file timeout" or something similar to that then close the emulator and run the app again
Otherwise post the logcat here to get better kind of solution
Make sure that the list of existing AVDs located in this folder
C:\Users\youruser\.android\avd
or test it this way :
1- right click in your app
2- run as => run configurations
3- Target Tab => manager
and post your error if you have any
you need to add application tag also in manifest.xml file.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
>
<activity
android:name=".SplahScreenActivity"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".OtherActivity"
android:screenOrientation="portrait" >
</activity>
</application>
When I create an Android project in Eclipse and send it to my device for debugging, the app works fine but when I try to uninstall it, I get a strange message. Below are the steps to recreate my problem:
Eclipse Version: 4.2.0 Build id: I20120608-1400
ADT Version: 2.0.3 v201208082019-427395
Run Eclipse
Click File->New->Project...
Select Android/Android Application Project
Click Next.
Enter Application Name: Test
Build SDK: Android 4.1
Minimum Required SDK: API 8 Android 2.2
Enable: Create custom launcher icon / Create project in workspace
Click Next thrice.
Click Finish.
Connect 4.1 Android device to computer via USB.
Click Run->Run from menu.
Select "Android application" on popup the "Run As" popup.
Click Ok.
MainActivity application runs on device.
Click the Back button on the Android device.
Open applications on device and find "MainActivity" app.
Long press the MainActivity icon and drag to trash.
Here's the puzzling part:
Instead of getting a standard
Do you want to uninstall this app?
I get a dialog with this text:
MainActivity is part of the following app: Test
Do you want to uninstall this app?
Why do I get this message instead of the standard one?
Why is MainActivity the name of the app when I specifically stated the name of the app is "Test"?
Additional Information:
If I go to Settings->Apps, the Application shows up as Test but is listed in my Launcher as MainActivity.
AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
The solution is to remove android:label="#string/title_activity_main" in the activity element.
The AndroidManifest.xml below solves the problem on Android 4.1.1 .
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Make sure your app name app_name is not styled.
Since I was using the app name somewhere else in the app I had made it bold, like this - In my strings.xml
<string name="app_name"><b>We are sons<b></string>
When I removed
<b></b>
tags, it worked.
Just keep it :
<string name="app_name">We are sons</string>
I do not know how to solve the first issue but the second can be solved in the following way. The problem is connected with Android new project wizzard. To solve this problem you can correct your manifest file in the following way and redeploy your project:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter android:label="#string/app_name" >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Do not forget to check what is the value of app_name. Some more details you can find in this post
I have been working on an Android 2.2 app for the past three months, but decided this past week to try to build the app using Android 2.1 SDK. The app ran fine under 2.2 in the emulator, and I was able to build the source as a 2.1 project successfully, but when I try to run the app in the 2.1 emulator, I get the following runtime error:
java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.tampamobileapps.testapp/.LoginScreen } from null (pid=-1, uid=-1) requires null
The app is not that complicated and only makes HTTP POST and GET requests. It also supports PayPal payments, but this API worked fine under 2.2. I have googled this error message and have not found any solutions to get rid of the error.
Any ideas?
Edit:
Here's the relevant parts of the Android manifest; the LoginScreen currently does nothing of consequence.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon"
android:debuggable="true"
android:label="#string/app_name"
android:name=".SharedApplicationContext">
<activity android:name=".LoginScreen"
android:label="#string/login_screen_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".LoginScreen"
android:label="#string/app_name">
</activity>
<activity android:name=".MainMenu"
android:label="#string/app_name">
</activity>
</application>
<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
</manifest>
You have duplicate activities defined in your manifest for .LoginScreen. Try removing:
<activity android:name=".LoginScreen"
android:label="#string/app_name">
</activity>
You may need to use the android:exported="true" option.
For instance, preference activities in live wallpapers need this set. Hope this helps someone else as I know you have probably already sorted the issue.
