my app is not running in android KITKAT [duplicate]

I want to change the minimum SDK version in Android Studio from API 12 to API 14. I have tried changing it in the manifest file, i.e.,
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="18" />
and rebuilding the project, but I still get the Android Studio IDE throwing up some errors. I presume I have to set the min SDK in 'project properties' or something similar so the IDE recognizes the change, but I can't find where this is done in Android Studio.

When you want to update your minSdkVersion in an existing Android project...
Update build.gradle (Module: YourProject) under Gradle Script and
make sure that it is NOT build.gradle (Project: YourProject.app).
An example of build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
buildToolsVersion "28.0.2"
defaultConfig {
applicationId "com.stackoverflow.answer"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dependencies {
androidTestCompile 'junit:junit:4.12'
compile fileTree(dir: 'libs', include: ['*.jar'])
}
Sync gradle button (refresh all gradle projects also works).
or
Rebuild project
After updating the build.gradle's minSdkVersion, you have to click on the button to sync gradle file ("Sync Project with Gradle files"). That will clear the marker.
Updating manifest.xml, for e.g. deleting any references to SDK levels in the manifest file, is NOT necessary anymore in Android Studio.

Update 2022
For Android Studio users:
Right click the App directory and
Choose the "Open Module Settings" (F4) option
Change the "Min SDK Version" in the Default Config tab
NOTE:
You might also want to change;
the "Target SDK Version" in the Default Config tab and
the "Compile SDK Version" in the Properties tab
Click Apply, then OK, and Gradle should automatically be synced
For users of older Android Studio versions:
Right click the App directory and
Choose the "Module Setting" (F4) option
Change the ADK Platform to what you need
Click OK and Gradle should automatically be synced

As now Android Studio is stable, there is an easy way to do it.
Right click on your project file
Select "Open Module Settings"
Go to the "Flavors" tab.
Select the Min SDK Version from the drop down list
PS: Though this question was already answered but Android Studio has changed a little bit by its stable release. So an easy straight forward way will help any new answer seeker landing here.

In android studio you can easily press:
Ctrl + Shift + Alt + S.
If you have a newer version of android studio, then press on app first.
Then, continue with step three as follows.
A window will open with a bunch of options
Go to Flavors and that's actually all you need
You can also change the versionCode of your app there.

In build.gradle change minSdkVersion 13 to minSdkVersion 8 Thats all you need to do. I solved my problem by only doing this.
defaultConfig {
applicationId "com.example.sabrim.sbrtest"
minSdkVersion 8
targetSdkVersion 20
versionCode 1
versionName "1.0"
}

According to this answer, you just don't include minsdkversion in the manifest.xml, and the build system will use the values from the build.gradle file and put the information into the final apk.
Because the build system needs this information anyway, this makes sense. You should not need to define this values two times.
You just have to sync the project after changing the build.gradle file, but Android Studio 0.5.2 display a yellow status bar on top of the build.gradle editor window to help you
Also note there at least two build.gradle files: one master and one for the app/module. The one to change is in the app/module, it already includes a property minSdkVersion in a newly generated project.

For the latest Android Studio v2.3.3 (October 11th, 2017) :
1. Click View on menu bar
2. Click Open Module Settings
3. Open Flavors tab
4. Choose Min Sdk version you need
6. Click OK

If you're having troubles specifying the SDK target to Google APIs instead of the base Platform SDK just change the compileSdkVersion 19 to compileSdkVersion "Google Inc.:Google APIs:19"

As well as updating the manifest, update the module's build.gradle file too (it's listed in the project pane just below the manifest - if there's no minSdkVersion key in it, you're looking at the wrong one, as there's a couple). A rebuild and things should be fine...

In Android studio open build.gradle and edit the following section:
defaultConfig {
applicationId "com.demo.myanswer"
minSdkVersion 14
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
here you can change minSdkVersion from 12 to 14

File>Project Structure>Modules
you can change it from there

When you want to change minimum SDK you should take care of minSdkVersion[About] in module build.garadle
android {
defaultConfig {
minSdkVersion 21
}
}

Changing the minSdkVersion in the manifest is not necessary. If you change it in the gradle build file, as seen below, you accomplish what you need to do.
defaultConfig {
applicationId "com.demo.myanswer"
minSdkVersion 14
targetSdkVersion 23
versionCode 1
versionName "1.0"
}

To change the minimum SDK version in Android Studio just...
1). Right click on "app" in the "Project" panel
2). Choose the new "Min SDK Version" on the "Default Config" tab
3). Click on "OK" and the project will now resync with the new Gradle settings.

For me what worked was: (right click)project->android tools->clear lint markers. Although for some reason the Manifest reverted to the old (lower) minimum API level, but after I changed it back to the new (higher) API level there was no red error underline and the project now uses the new minimum API level.
Edit: Sorry, I see you were using Android Studio, not Eclipse. But I guess there is a similar 'clear lint markers' in Studio somewhere and it might solve the problem.

Gradle Scripts ->
build.gradle (Module: app) ->
minSdkVersion (Your min sdk version)

Set targetSdkVersion = 22 still need in app permission for Marshmallow device? [duplicate]

I want to change the targetSdkVersion from 19 to 18 in Android Studio (not Eclipse), but failed.
Android Studio complains the following after I changed the targetSdkVersion, and resync the project with Gradle files:
Execution failed for task ':(project name):processDebugManifest'.
> Manifest merging failed. See console for more info.
From the console I found that it is the library I added to the gradle dependencies using the old targetSdkVersion value.
[(Code Directory)\main\AndroidManifest.xml, (Code Directory)\build\exploded-bundles\(Library Directory).aar\AndroidManifest.xml:2] Main manifest has <uses-sdk android:targetSdkVersion='18'> but library uses targetSdkVersion='19'
I learn that in Android Studio, the targetSdkVersion and minSdkVersion flags are defined in the build.gradle file. The project is created with Android Studio's "New project" wizard, and there is NO tag in my code's AndroidManifest.xml. So the problem should not be the two values out of sync. According to the above message, the targetSdkVersion value in the main manifest is what I want.
So the problem should be in the manifest file of the library. I open the library's AndroidManifest.xml file and found the following line:
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="19"/>
Obviously it isn't correct. The problem is that the file is not for manual modification. I tried changing the targetSdkVersion value, and even tried removing the declaration, but it comes back every time I build the project.
I tried cleaning the project, still no luck.
So my question is: Is there a "right" way to alter the targetSdkVersion in Android Studio which I am not aware of?

Here's how to change the targetSdkVersion and minSdkVersion in Android Studio.
Step 1
Open build.gradle - Path\Your_Application\app\build.gradle.
defaultConfig {
minSdkVersion 8
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
Change the targetSdkVersion and minSdkVersion values to what you desire.
Step 2
In the Android Studio menu, find "Build" (Alt + b in Windows) and choose "Clean project".

Alternatively, click on File > Project Structure > Application > Flavours > Min Sdk Version and press ok on change. You can also change the Target Sdk Version as well. I think this is a neater approach to editing the gradle build file directly.

in build.gradle
Change these values according to current project Updation
in sdk manager
compileSdkVersion 25
buildToolsVersion "25.0.2"
minSdkVersion 15
targetSdkVersion 25
in dependencies replace below code
compile 'com.android.support:appcompat-v7:25.1.0'
and synchronise project

Android Studio - Unable to run app on device minSdk(API 23, N) != device Sdk(API 22)

so i reinstalled linux on my computer and after i reinstalled android studio i tried getting an app that i wrote on to my phone which previously had not been a problem. The App ist targeted at devices with API 16 or higher but apparently Android Studio now features something called N preview which does not let me run anything on my phone. specifically when i hit the run button it tells me that
minSdk(API 23, N) != device Sdk(API 22)
i know this seems as though the target API isnt set correctly but when i started the project i set it to 16. Now how do i get around this? Also whats the cleanest way to change the target API on a project? Do i just change the build gradle?
Thanks a lot!
app gradle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 'android-N'
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.example.josias.myapplication"
minSdkVersion 16
targetSdkVersion 'N'
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.+'}

Change
compileSdkVersion 'android-N' to compileSdkVersion 22 and targetSdkVersion 'N' to targetSdkVersion 22

The same happened to me on Android Studio, so I could not start a new emulator.
I had to:
Gradle Scripts -> build.gradle (module:app) -> minSdkVersion 14
(update "minSdkVersion" value to "14".
Now I am able to start a new emulator.

See the explain of CommonsWare. The key point is a preview version, so
older level device was prevented to install app anyway when using N compileSdkVersion.

This wortk for me in Android Studio: hold ctl+alt+shift press 'S', This will open project structure. Click on the tab 'Flavors', check in min sdk version if appear a version of your device sdk if you see select it and click 'OK', but if you didn't see a option for your sdk device click on cancel. Go to build.gradle(app) file and type in the min sdk version the version of your sdk device(android studio will recomend you to intall the version sdk). After that hold ctl+alt+shift press 'S' and the version sdk min will be there, just select it and click 'ok'. :)

check your build.gradle file to ensure the proper min sdk is set...android studio overrides the manifest with the build.gradle

I renctly encountered this problem, and this is very strange, on the other thread there's people suggest you should change you usb setting to "MTP/FTP" or something, this doesnt make sense and dont work out on my case.
After search some example case in this problem, I found that most of people have this problem when minSDK/'targetSDK'/'compileSdkVersion' is not a int but a letter.
I changed my MNC/N' to 23, andbuild - clean build`, problem solved.
hope it can help someone.

Change the minSdkVersion to your target device sdkVersion in build.gradle(Module:app)file will be appear on left side in Gradle Scripts.. Ex: minSdkVersion 24 //change the version value to ur target device value(like 23 or 22 or 21 or etc)
According to your configuration you have to change the minSdkVersion 23 to minSdkVersion 22, becoz your target device at API LEVEL 1

you can do a thing just open the sdk manager since i had one and just install ,the ÄNDROID N (API 23 N PREVIEW PACKAGES) give it a try instead of changing the gradle files

Changing the minSdkVersion may not always help. Check your SDK Manager, as already suggested, and make sure that you have the necessary versions installed as well (I had changed mine in Gradle, but it only made things worse on my end).

Android Studio: How to debug older version of Android SDK step-by-step

I have an Android project targetting the Android SDK v21. Now I need to debug it on a device with Android 4.4 (i.e. SDK v20). How do I tell Android Studio to attach an older version of the source to the internal classes so that I can step through them?

Here the best solution is to set compile SDK version to 20. So that build tools will compile your project using SDK version 20 and you can debug your app.
When you use several modules in your project you need to set same compile SDK version to each module.

I can not confirm my answer works, but it is working for me.
I replace my compileSdkVersion, buildToolsVersion, minSdkVersion and targetSdkVersion with new one like following in my build.gradle file.
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.example.mytest"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
After changing it, you may not need to convert old to new or new to old sdk component.

You need to open module settings (Right click on your app module and select Open Module Settings or just select module and press ⌘ + ↓ on Mac)
And select compileSdk and buildTools to v20
Another way to do it is to open build.gradle file for the "app" module to change compileSdk and buildTools.

I would like to explain little before the solution.
Google provides the SDK APIs in the form of JAR (android.jar) files. The JAR files are stored at SDK LOCATION\platforms\android-API#.
For example the android.jar file for the Android 4.4(Kitkat) API-19 is located at YOUR SDK LOCATION\platforms\android-19\android.jar.
The Gradle compilation with the Android Studio uses the compileSdkVersion field in the build.gradle to select a specific android.jar for the compilation.
What is compileSdkVersion?
The version of the API the app is compiled against.
This means you can compile and use Android API features included in that version of the API
All the previous version features are also included during compilation.
If you try and use API 21 feature, such as public void openCamera (String cameraId, CameraDevice.StateCallback callback, Handler handler)
Added in API level 21 but set compileSdkVersion to 20, you will get a compilation error.
If you set compileSdkVersion to 21 you can still run the app on a API 20 device as long as your app's execution paths do not attempt to invoke any APIs specific to API 21.
How to set compileSdkVersion?
There are two ways
1. Selecting API from the GUI
1) Select "File->Project Structure..."
2) Select "app->Properties"
3) Set the "Compile Sdk Verion" from the drop down box to the required SDK version.
4) "compileSdkVersion" will be set automatically in the "app" module's
"build.gradle" file.
2. Setting the API in the gradle.build file
1) Open the build.gradle file of the "app" module
2) Set the compileSdkVersion to required value such as 19 for the API#19.
I hope that helps...
Happy Coding...

The best solution for me was to add a new module (Android Library) to the project and set the compile SDK to the requested api level. That way you can still compile your main app with the original SDK level but still get the sources integrated with your debugging Android version.

You can create a new Android Virtual Device with the preferred API level and debug the application on it.

Simply open module settings and change compileSdk and buildTools to v20
