I want to use OpenCV4Android in Android Studio. I downloaded OpenCV for Android from this link:
http://opencv.org/downloads.html
But, when I try to import it, I get different errors in Camera2Renderer.java like, Cannot resolve symbol 'camera2', Cannot resolve symbol 'CameraDevice', Cannot resolve symbol 'Size', and Cannot resolve symbol 'CaptureRequest'.
I have tried both methods available here:
OpenCV in Android Studio
http://answers.opencv.org/question/14546/how-to-work-with-opencv4android-in-android-studio/
But, I get the same error.
Can anyone please tell me how to solve this error to be able to use openCV?
Thank you.
I faced the same issue while configuring OpenCV SDK with Android Studio.
I am using the latest SDK build of OpenCV : OpenCV-3.1.0-android-sdk
Please ensure that you have configured your build.gradle scripts.
Build.gradle(Module: app) -->
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "com.example.dev.opencvapp"
minSdkVersion 15
targetSdkVersion 24
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
sourceSets { main { jni.srcDirs = ['src/main/jni', 'src/main/jniLib/'] } }
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.2.1'
compile project(':openCVLibrary310')
}
Build.gradle(Module: openCVLibrary310) -->
apply plugin: 'com.android.library'
android {
compileSdkVersion 24
buildToolsVersion "19.1.0"
defaultConfig {
minSdkVersion 8
targetSdkVersion 21
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
After doing this you should be able to build the app with out any errors.
I hope I helped you!!

I recently (3 days ago) started learning Android Studio. I bought an Eclipse game project to play with, but I am getting errors. And when I fix that error, I get a new error.
The current one that I can't seem to fix is:
Error:(2, 0) Could not find method defaultConfig() for arguments

compile files('libs/javax.inject-1.jar')

compile files('libs/support-v4-19.0.1.jar')
}
Anyone know why I am getting the error?
Here's a screenshot:
Thank you very much for your time and assistance in this matter.
This is because you didn't add code for android application plugin which is apply plugin: 'com.android.application'. You also need to move the defaultConfig inside the android like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.3"
defaultConfig {
...
}
}
dependencies {
...
}
I have an Android project and I use Android Studio. In this project, I have the main app (cdmandroidclient) and the SDK (cdmsdk) which is the core lib.
I added recently a library built with Java 8 into my Android project. So I had to change a few things into my Gradle files :
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.1"
defaultConfig {
applicationId "com.mycompany.cdmandroidclient"
minSdkVersion 15
targetSdkVersion 24
versionCode 1
versionName "1.0"
jackOptions {
enabled true
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
minifyEnabled false
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile project(path: ':cdmsdk')
compile 'com.android.support:appcompat-v7:24.2.0'
}
As you can see, I import into my app, the cdmsdk module, which is part of my project. Before using Jack, everything was fine.
Now, when I try to build the app I get errors for resolving dependencies of my module "cdmsdk" into my app "cdmandroidclient".
Exemple of an error :
Error:E:\Workspace\CDMAndroidClient\app\src\main\java\com\mycompany\cdmandroidclient\service\CdmService.java:16:
The import com.mycompany.cdmsdk.heartbeat.Security cannot be resolved
I don't understand what's happening, because the main app dependencies have not changed and still reference the SDK with :
compile project(path: ':cdmsdk')
The Gradle build fail as I said, during the task :app:compileDebugJavaWithJack
Any idea ? Thank you very much :) !
EDIT : It's the exact same thing as Javac and with Java 7... don't know what I've changed but my app can't use cdmsdk dependencies anymore ... wtf
I have an an Android Studio project A which is an app, and a project B which is a library project. I have included project B in project A. Project B has some dependencies (android async http, and org.json) that are used in both project B and project A. I upgraded Android Studio to 2.2 Preview 2, and am now having an issue where all of my usages of android async http are saying Cannot Resolve Symbol. However, my JSON usages are just fine. When I build the project, I get no errors and can run it just fine. How can I fix the Cannot Resolve Symbol issue in Android Studio?
I have tried
cleaning & rebuilding both projects
making a change in the app's build.gradle & syncing grade
re-arranging the order of dependencies
sync project with gradle files
delete android async http.xml from .idea/libraries & sync project with gradle files
opening and closing android studio
setting minifyEnabled=true in the app & library
Is there something I am missing?

I am new to Android Studio and was just trying to import my eclipse project. i am trying to resolve this issue for quite a while now but unable to.
I have a mainactivity project which uses mmany other libraries staggeredgridview, devsmart, google maps and appcompactv7. I am getting following 2 errors.
Note: mainactivity project is the one which i am working on and uses other external libraries.
Error:(7, 5) uses-sdk:minSdkVersion 8 cannot be smaller than version 9 declared in library B:\Android Studio Projects\mainActivity\build\intermediates\exploded-aar\com.google.android.gms\play-services\6.5.87\AndroidManifest.xml

Just edit minsdk of your build.gradle of mainactivity to 9 :
defaultConfig {
applicationId "com.example.staggeredgridviewdemo"
minSdkVersion 9 // changed line
targetSdkVersion 16
}
Note : Also did the same for other libs if there minsdk is small then 9
Please open your manifest file and write the bellow code it will work
<uses-sdk tools:overrideLibrary="com.google.android.gms"/>
and add the list of libraries for uses-skd separated by comma
Go to all the manifest files or build.gradle files of all the projects and make the minSDKversions the same.8 for instance.
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'

buildToolsVersion "19.1.0"
defaultConfig {

}
}
}
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.+'
}
