So I'm getting the MainActivity does not exist error, it might be because I renamed the package and app from bomber to Bomber and changed the appId from com.bomber to cool.bomber.android
I've checked the AndroidManifest, the activity source files and the build.gradle file but I can't seem to find what's the mistake
Error message
Starting: Intent { cmp=cool.bomber.android/.MainActivity }
Error type 3
Error: Activity class {cool.bomber.android/cool.bomber.android.MainActivity} does not exist.

I'm not sure what else I should be looking at to debug.
You need to uninstall the application properly.
If it does not work from the phone, you can use cmd
adb uninstall "package name"
Add package name in manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="cool.bomber.android">
and still not working than write full package name like this
<application
android:name="cool.bomber.android.MainApplication"
android:allowBackup="true" >
<activity
android:name="cool.bomber.android.MainActivity"
>
and make sure this is the right path
and in CMD write this:
cd android & gradlew clean
or maybe
cd android && ./gradlew clean
and than run react-native run-android
Make sure when you write this code you are at root of your project folder
Or Else:
Follow this to refresh whole project after changing package using android studio.
For me the problem was that I had added tools:node="replace" to my android/app/src/debug/AndroidManifest.xml:
<application android:usesCleartextTraffic="true" tools:targetApi="28" tools:ignore="GoogleAppIndexingWarning" tools:node="replace"/>
I had added that based on someone recommending it for some other issue and it caused the infamous Error type 3 to appear. Once I got rid of it, the problem went away:
<application android:usesCleartextTraffic="true" tools:targetApi="28" tools:ignore="GoogleAppIndexingWarning"/>
Cheers,

I had to reinstall the app for the problem to be resolved

After i have created my own appplication class:
package com.example.bezzabarovaa.myapplication;
import android.app.Application;
import android.content.Context;
/**
* Created by bezzabarovaa on 04.08.2017.
*/
public class app extends Application {
public static Context context;
#Override public void onCreate() {
super.onCreate();
context = getApplicationContext();
}
}
and have changed manifest.xml (changed application to app class)
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bezzabarovaa.myapplication">
<app

<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" />
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</app>
I`ve got a message Error running Unnamed: Default Activity not found
If I will change my classapp back to application in manifest.xml - everything is ok.
Where is a problem?
Thank you.
This <app is supposed to be <application you specify your custom app in here:
<application android:name=".app" ...
Check the documentation the name section says:
The fully qualified name of an Application subclass implemented for
the application. When the application process is started, this class
is instantiated before any of the application's components. The
subclass is optional; most applications won't need one. In the absence
of a subclass, Android uses an instance of the base Application class.
Full example (with your code):
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bezzabarovaa.myapplication">
<application
android:name=".app"
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=".MainActivity"
android:label = "#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>
</manifest>
Solved by clicking the "Sync project with gradle files"
I faced the same problem a while ago, after changing my default activity to another.
What solved it was invalidate caches and restart Android Studio:
File -> Invalidate Caches / Restart...
and then clicking on Invalidate and Restart.
Use below code snippet
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bezzabarovaa.myapplication">
<application
android:name=".app"
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=".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>
You can get Android Studio not to complain by going to the "Edit Configurations" menu (tap "Shift" three times, type "Edit Configurations"), then change Launch Options > Launch to "Nothing".
I'll probably add a generic activity containing instructions, just to avoid any confusion.
Add below line in your manifest application tag
<application
android:name=".app"
...
</application>
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</activity>
<activity android:name="com.example.android.bluetoothlegatt.DeviceControlActivity" />
<service android:name="com.example.android.bluetoothlegatt.BluetoothLeService" />
</application>
</manifest>
I solved the very same issue by following steps
Close Android Studio
deleting from :
C:\Users\your user name.android/log and gradle folder
C:\Users\your user name.gradle
from C:\Users[your user name]
Restart Computer and run Android studio (it Will take some time to rebuild)
I want to make register_activity is first run if application open. But, still MainActivity run first. Can anybody help me to fix this.
This is my Manifest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.client18.dd">
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/Theme.AppCompat.DayNight.NoActionBar">
<activity android:name=".register_activity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".signup_activity">
</activity>
<activity android:name=".MainActivity">
</activity>
</application>
</manifest>
When I see your Manifest file I can not see any faults. I suggest to do followings.
1) Uninstall app in emulator / device if its exists, and then run application.
or
2) Rebuild project with cleaning ( Build > Clean Project )
P.S.
If you could practice signup_activity > SignupActivity it is nice and best practice.
This error keeps comes on my phone but it did not come before,I saw all the stack overflow methods but non of them could help me.
I get this error when I test the app from android studio to my phone.I tried on other phones too but still the problem exist.
This is my manifest:

Main tag of manifest file must be manifest. Instead of xml tag, write something like:

android:versionName="1.0.0" >

android:supportsRtl="true"
android:theme="#style/AppTheme">
...
</application>
</manifest>
As you are using Android Studio, I believe that you are likely have the problem mentioned in this question, and as mentioned here in the answer this error happens when you change the build version for your project (like downgrading or upgrading):
I've been working on this same exact problem for the last 8
hours...you've had no issues after rolling back from 2.0 to 1.5.1?
I've noticed that, even with the error, running the app works fine
sometimes.
so you have to make sure that there is no problem with the new release you are using, then you have to clean and rebuild your project again like mentioned here.
Or you can use the following hint from this answer:
Remove the .idea folder and gradle folder, then click button sync
project with gradle gradle files, after this process finished, you are
able to run your app as normal.
When running my app on my device straight from android studio, its running fine when deployed but its not actually installing - as in no icon in the menu etc (but it is in the settings under apps). Any help to solve would be great.
manifest is below.

thanks in advance
Contrary to popular belief the action of this intent filter is not supposed to contain the activity's class name. This should fix it:
<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>
It is definitely installed on the phone, if it was run on the phone.
You could try compiling the apk and manually installing with adb:
I assume you are using gradle to build:
From project directory root:
View build tasks:
./gradlew tasks
./gradlew assembleDebug
The apk would be created in app/build/outputs/apk/
Now cd to that directory and run:
adb install my-app.apk
Make sure your device or emulator is connected
I'm beginner in Java Android developing. I'm using Eclipse SDK 3.6.1 version. I'm trying to do this thing: in first class (layout - main.xml) is button "hello", it calls new class (layout - second.xml), in this class are button "hello2", it calss new class. I can't do this cause when I push first button "hello" I getting this messages "The aplication (xxxx) has stopped unexpectedly. Please try again". How to resolve this problem. I think problem is in AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.kodinis_raktas"
android:versionCode="1"
android:versionName="1.0">

<activity android:name=".veiksmas"
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=".second" >
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity android:name=".lock"></activity>
<intent-filter>
</intent-filter>
</application>
<uses-permission android:name="android.permission.SEND_SMS">
</uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS">
</uses-permission>
<uses-sdk android:minSdkVersion="3" />
</manifest>
Use adb logcat, DDMS, or the DDMS perspective in Eclipse to examine LogCat and look at the stack trace associated with your error. That will give you more information.
I would recommend getting rid of the <intent-filter> elements from .second and .lock, since you are not using them. If your error is coming from trying to start .second, the existence of your category-only <intent-filter> may well prevent that activity from being started.
In my limited experience with android I think you need to add this line after activity android:name=".second"
android:label="#string/app_name">
