Android Studio "cannot resolve String character"

I have a small project that was launched in Eclipse. Then I exported it to a gradle file and imported it into AS (0.5.7).

At first, it didn’t work as much as it should, but after the “build => make” project I didn’t get any highlighted errors or so.

So, I tried to run the application on an emulated device. Well, the device never started, and now I get red squiggly strings under the mentions of "String", "ArrayList", etc., Saying that "cannot resolve the character".

What is f?

I tried to clean and rebuild, as well as "synchronize the project with gradle files".

Where do I go next? I want to develop in AS so badly!

Contents of build.gradle:

buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.9.+' } } apply plugin: 'android' dependencies { compile fileTree(dir: 'libs', include: '*.jar') } android { compileSdkVersion 19 buildToolsVersion "19.0.1" sourceSets { main { manifest.srcFile 'AndroidManifest.xml' java.srcDirs = ['src'] resources.srcDirs = ['src'] aidl.srcDirs = ['src'] renderscript.srcDirs = ['src'] res.srcDirs = ['res'] assets.srcDirs = ['assets'] } // Move the tests to tests/java, tests/res, etc... instrumentTest.setRoot('tests') // Move the build types to build-types/<type> // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ... // This moves them out of them default location under src/<type>/... which would // conflict with src/ being used by the main source set. // Adding new build types or product flavors should be accompanied // by a similar customization. debug.setRoot('build-types/debug') release.setRoot('build-types/release') } }

Easier and I think more correct:

Just select the menu item "File / Invalid Cache / Reboot ..."

For me, this successfully resolved the problem (caused by an unexpected shutdown of the PC)

Therefore, the location of the project should be as follows:

  • Create an application folder in your project.
  • in the application folder, create the following folders: libs and src
  • inside src create the main folder
  • inside main create java and assets
  • moving contents of old src in java
  • moving contents of old libraries to libs
  • move res folder to src
  • move AndroidManifest.xml to src
  • move resource folder to src
  • create build.gradle inside the application folder with the following contents:
 apply plugin: 'android' dependencies { compile fileTree(dir: 'libs', include: '*.jar') } android { compileSdkVersion 19 buildToolsVersion "19.0.1" }
  • create settings.gradle in the root of the project with the following contents:

enable 'app'

  • build.gradle in the root folder should have the following structure:

buildscript {repositories {mavenCentral ()} of dependencies {classpath 'com.android.tools.build: gradle: 0.9. +'}}

Remove the following line from the file reporting the error, if any.

 import static com.google.android.gms.internal.aR;
