I imported the opencv android library to my android studio and the Camera2Renderer class has a lot of compiler errors because the android.hardware.camera2 classes can't be imported.
I solved the problem. Jim was right, I did not have the correct target API. For the next person who has this problem and finds this thread, the solution is that you have to make sure that the build.gradle files for your project and your OpenCV match.
I am working with openCVLibrary3.2.0 and trying to run its sample and faced same issue but I changed gradle files for both mysampleApp and openCVLibrary320 module as below
This is my app build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "org.opencv.face"
minSdkVersion 9
targetSdkVersion 21
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_5
targetCompatibility JavaVersion.VERSION_1_5
}
ndk {
moduleName "native_sample"
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
externalNativeBuild {
ndkBuild {
path 'src/main/jni/Android.mk'
}
}
}
dependencies {
compile project(path: ':openCVLibrary320')
}
and this my OpenCV library module build.gradle file
apply plugin: 'com.android.library'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
minSdkVersion 9
targetSdkVersion 21
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
Note:
things to notice are that compileSdkVersion, buildToolsVersion, minSdkVersion, and targetSdkVersion these must be same for all gradle files
I changed the compileSdkVersion from 14 to 23
and buildToolsVersion to "23.0.2"
this solved the camera2 import related issue
I am working on openCVLibrary330 trying to run its sample and faced same issue but i changed gradle files for openCVLibrary330 module as below
This is my app build.gradle
apply plugin: 'com.android.library'
android {
compileSdkVersion 23
buildToolsVersion "26.0.2"
defaultConfig {
minSdkVersion 8
targetSdkVersion 21
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
I had the same problem. But, as many people have suggested I didn't had to change the gradle files to match exactly the same. I changed my compileSdkVersion and buildToolsVersion to the same on both gradle files, the rest are different. Its working fine now.

I'm pretty new to Android development (and gradle). I'm trying to set up the openCV sdk within a new project. The code in the Application/build.gradle file is as follows:
apply plugin: 'com.android.library'
android {
compileSdkVersion 27
buildToolsVersion "27.0.3"
defaultConfig {
minSdkVersion 21
targetSdkVersion 27
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
The opencv/build.gradle is:
apply plugin: 'com.android.library'
android {
compileSdkVersion 27
buildToolsVersion "27.0.3"
defaultConfig {
minSdkVersion 21
targetSdkVersion 27
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
And the settings.gradle is:
include 'Application'
include ':opencv'
I get the error in the title when I try to sync the project. Any explanation or help is appreciated. I've looked at a few other similar threads and tried some suggestions in them but nothings worked so far. Thanks!
This is my build.gradle file
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
buildTypes {
debug {
debuggable true
}
}
defaultConfig {
applicationId "com.wokoshop.sony.app"
minSdkVersion 14
targetSdkVersion 25
versionCode 32
versionName "4.16"
multiDexEnabled = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
I am seeing following error in my all java files.
The SDK platform-tools version (23.1) is too old to check APIs compiled with API 25.
I am not using/seeing anywhere 23.1?
Why this error? how to fix this?
I Have build my app in android 6 without any error, but when I build my app in android 4.4.2 I get this error
This app has been built with an incorrect configuration.
Please configure your build for VectorDrawableCompat.
and this is my gradle:
android {
compileSdkVersion 24
buildToolsVersion "23.0.0"
defaultConfig {
applicationId "com.faranegar.channel"
minSdkVersion 11
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
note: when I set compileSdkVersion 23, every thing is fine and there isn't any error.
This worked well for me
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.example.app"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
generatedDensities = []
}
// This is handled for you by the 2.0+ Gradle Plugin
aaptOptions {
additionalParameters "--no-version-vectors"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
Notice this in the above code:
// This is handled for you by the 2.0+ Gradle Plugin
aaptOptions {
additionalParameters "--no-version-vectors"
}
and
generatedDensities = []
UPDATE
If this generatedDensities = [] is showing deprecated, use the following instead.
vectorDrawables.generatedDensities = []
Hope it helps
This issue was alread reported here Issue 214182: appcompat-v7 24.0.0 is incompatible with rasterized vectors.
One of the developer mention:
What version of the Gradle plugin are you using?
As of v2.0 of the Gradle plugin, library resources are never
rasterized so this should never happen.
The workaround for this is to update your Gradle by following this official link. Android Plugin for Gradle Release Notes.
buildscript {
...
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
}
}
if you are using rasterized vector drawables
for Gradle plugin 2.0+
android {
defaultConfig {
vectorDrawables.useSupportLibrary = true
...
}
}
for Gradle plugin before 2.0
android {
defaultConfig {
generatedDensities = []
...
}
aaptOptions {
additionalParameters "--no-version-vectors"
}
}
you should add appcompat-v7 23.2.0+ to your build.gradle.for me,i am using
compile 'com.android.support:appcompat-v7:23.4.0'
This happened to me while implementing unit tests with JUnit and Robolectric. If that's your case maybe you need to add this to your gradle file, inside the android section. That's how I fixed it:
testOptions {
unitTests {
includeAndroidResources = true
}
}
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.
Im really stuck whit this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion '20.0.0'
defaultConfig {
applicationId "com.example.testing"
minSdkVersion 14
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile project(':External-Module')
}
I dont know what to do... I cant build project and use dependencies from External module.
the error is:
Error:(7, 47) error: package com.example.android.transfer does not exist
Error:(19, 9) error: cannot find symbol class ClientData
Error:(19, 25) error: cannot find symbol variable ClientData
Error:Execution failed for task ':Testing:compileDebugJava'.
but inside the IDE all is well and I can see the module
Here is also the External Module
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion '20.0.0'
defaultConfig {
applicationId "com.example.externalmodule"
minSdkVersion 14
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
}
Your "External-Module" is an Android library, so according to the Gradle+Android documentation instead of
apply plugin: 'com.android.application'
it should be
apply plugin: 'com.android.library'
// Old version of the plugin
// apply plugin: 'android-library'
Also, make sure the imports in your app matches the package you are overriding in your library build script. Looks like the app is not founding com.example.android.transfer but the library package really is com.example.externalmodule
