Problems importing an Eclipse project into Android Studio

I created my first Android app 2 years ago in Eclipse and now I have some time to improve it. I do not have Eclipse installed anymore, so I decided to import the project into Android Studio.
But now I am running into several problems:
Manifest merger failed : uses-sdk:minSdkVersion 8 cannot be smaller than version 14 declared in library [com.google.android.gms:play-services:10.2.0]
So in the build.gradle I changed it to 14. Then I got the next error
Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Spinner.Underlined'.
So therefor I changed the compileSdkVersion and the targetSdkVersion to 25 (correct me if it's wrong). And I changed
compile 'com.android.support:support-v4:20.0.0'
into
compile 'com.android.support:support-v4:25.2.0'
Now I could build my project. But when I tried to run my app, after more then 5 minutes(!) I got the next error :
Error:The number of method references in a .dex file cannot exceed 64K.
Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html
So then I added
multiDexEnabled true
and
compile 'com.android.support:multidex:1.0.1'
and
android:name="android.support.multidex.MultiDexApplication"
to the manifest file.
My build.gradle now looks like this
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "<<myApplicationId>>"
minSdkVersion 14
targetSdkVersion 25
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:25.2.0'
compile 'com.google.android.gms:play-services:+'
compile files('libs/AppFireworks.jar')
compile files('libs/fcvtgzwtzuliivdcu.jar')
compile 'com.android.support:multidex:1.0.1'
}
But now I got the following pop-up and errors
Instant Run does not support deploying build variants with multidex enabled, to a target with API level 20 or below. To use Instant Run with a multidex enabled build variant, deploy to a target with API level 21 or higher.
Error:UNEXPECTED TOP-LEVEL ERROR:
Error:java.lang.OutOfMemoryError: GC overhead limit exceeded
Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: java.lang.UnsupportedOperationException
What have I done wrong? Do I have to change the minSdkVersion to 21? I want to be able to run my app on Android 4.x. I could when I was developing in Eclipse. So far switching from Eclipse to Andriod Studio is going from bad to worse. :-(

you are compiling using compile 'com.google.android.gms:play-services:+'
play service is itself is a large library. You should not use + which implies all available version to compile
Rather use a specific version of play services or break down the library and use specific services like location,maps etc.
Also u can use dexOptions to increase ur memory usage during compilation
try changing your gradle file to:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "<<myApplicationId>>"
minSdkVersion 14
targetSdkVersion 25
multiDexEnabled true
}
dexOptions {
incremental true
javaMaxHeapSize "4g"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:25.2.0'
compile 'com.google.android.gms:play-services-maps:9.0.1'
compile 'com.google.android.gms:play-services-plus:9.0.1'
compile 'com.google.android.gms:play-services-location:9.0.1'
compile 'com.google.android.gms:play-services-games:9.0.1'
compile 'com.google.android.gms:play-services-gcm:9.0.1'
compile files('libs/AppFireworks.jar')
compile files('libs/fcvtgzwtzuliivdcu.jar')
compile 'com.android.support:multidex:1.0.1'
}

How to implement Robobinding in android app

I'm trying to implement the MVVM architecture using Robobinding. Here's the link I'm following for the Environment setup of Robobinding in Android Studio(without AspectJ):
http://robobinding.github.io/RoboBinding/getting_started.html#_android_studio
This is what my app level Build.gradle looks like after adding the dependencies:
apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.example.simpletimerapp"
minSdkVersion 14
targetSdkVersion 23
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-v7:23.1.1'
compile "org.robobinding:robobinding:${robobindingVersion}"
}
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.+'
}
}
The problem is gradle build fails with the following error:
Error:(26, 0) Could not find property 'robobindingVersion' on org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler_Decorated#2ccd2d42.
Open File
EDIT 1:
On replacing ${robobindingVersion} in the dependencies block with 0.8.12 (latest version of robobinding), gradle build finishes successfully. But now, I'm unable to use the "bind" attribute in the views in my layout files. This is the error:
Unexpected namespace prefix "bind" found for tag TextView
EDIT 2:
Still can't find the solution. So, I downloaded this minimal android app (from their official github page) which implements robobinding and edited it to create my own app. It's working fine now.

how to import libraries to android studio? (Android manifestmerger file)

I know this sounds very easy, but android studio is eating my brains out. I know how to import my current project say myProject in to ADT very easily. But I came to know that soon the support for adt will be ending. So i decided to switch to Android studio. I am using the following libraries in my project
Commons
ActionBarSherlock
AndroidImageChacheMaster
SlidingMenuMaster
I tried to import the project myProject.
See its Project.Properties file
# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system use,
# "ant.properties", and override values to adapt the script to your
# project structure.
# Project target.
target=android-21
android.library.reference.1=../actionbarsherlocklibrary
android.library.reference.2=../Android-Image-Cache-master
android.library.reference.3=../Commons
android.library.reference.4=../google-play-services_lib
android.library.reference.5=../SlidingMenuMaster
When i tried to import it A.S told me unrecoverable errors and I pasted the library folder as instructed by android studio.
And it project was imported succesfully
but there are two error apparing in the log
/home/mukund/StudioProjects/aftercrash62/commenorkingandroid/build/intermediates/manifests/tmp/manifestMerger2026412193483179673.xml

}

If you have added Sherlock as an AAR dep like
compile 'com.actionbarsherlock:actionbarsherlock:4.4.0#aar'
you can remove
compile project(':actionbarsherlocklibrary'), include ':sherlock' line from your settings.gradle, then related folder from your project.
And your targetSdkVersion can be the same as your compileSdkVersion as well.

Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'

I am getting an ':app:packageAllDebugClassesForMultiDex' Error when I try to build an application using the YouTubeData API. I have researched several other threads that cover this error and the conclusion that I have come to is that I have libraries in my build file that are creating a duplicated reference to build files. I know that the file triggering the error is:
'com/google/api/client/googleapis/json/GoogleJsonErrorContainer.class'
but how do I exclude the reference from the build file with out removing the entire library?
This is my build file
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "co.hannalupi.fitnessblenderapp"
minSdkVersion 16

multiDexEnabled true

compile 'com.google.apis:google-api-services-youtube:v3-rev136-1.20.0'
}
This is the error I get:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: com/google/api/client/googleapis/json/GoogleJsonErrorContainer.class
I am new to Android, any direction you can point me in would be greatly appreciated. Thanks in advance.

An update for folks having a similar error - As a last resort I deleted the project file that I was working in from my desktop and cloned a fresh copy from GitHub. Importing and running the fresh copy gave me no errors!!

Can't import an eclipse project into android studio?

I am trying to learn android in android studio.Now i imported an eclipse project in android studio and now while trying to run it it is not building.Some problems in gradle may be..
Error:Execution failed for task ':app:processDebugManifest'.
Manifest merger failed : uses-sdk:minSdkVersion 8 cannot be smaller than version L declared in library com.android.support:support-v4:21.0.0-rc1
my build.gradle
apply plugin: 'android'
android {
compileSdkVersion 19
buildToolsVersion "19.1.0"
defaultConfig {
applicationId "com.example.practise"
minSdkVersion 8
targetSdkVersion 19

buildTypes {
release {

}
}
}
dependencies {
compile 'com.android.support:support-v4:+'
compile 'com.android.support:gridlayout-v7:+'
}
Can anyone help me to find out the problem??

Change your dependencies
dependencies {
compile 'com.android.support:support-v4:19.1.0'
compile 'com.android.support:gridlayout-v7:19.1.0'
}
Using the +, you are getting the last release.
Currently the last release is the compile 'com.android.support:support-v4:21 and it has a minSdk='L' because it is a preview release.
Use it only to test the android 'L' preview.

Try editing the following line to your Android Manifest file, like so:
dependencies {
compile 'com.android.support:support-v4:21+'
}
Then your project should build.

Change your dependencies in app/build.gradle to lower version
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "com.eusecom.snowsmsden"
minSdkVersion 16
targetSdkVersion 20
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:20.+'
compile 'com.android.support:appcompat-v7:20.+'
}
