Using Android studio to develop a collection of problems encountered

Transferred from: http://blog.csdn.net/yuxiangyunei/article/details/26682015

Issue one: After importing samples in the SDK, Messages prompts "Error:Cause:failed to find target android-19.0.1" Install the missing platform fro M the Android SDK Manager.

Cause: As installed, the Build-tools version comes with 19.0.3, and the example is created under 19.0.1.

Resolution: 1, use the SDK Manager to install the 19.0.1, 2, modify Project->app->build.gradle in the Buildtoolsversion "19.0.1" changed to Buildtoolsversion " 19.0.3 ".

In addition, if the sample is imported from the Internet, it is generally necessary to modify compilesdkversion to 19.

Issue two: After installing the new version of the JDK, the old version of the JDK is still used at compile time

Workaround: Adjust file->project structure->sdk location and File->other Settings->default Project in as in addition to updating JAVA_HOME environment variables STRUCTURE->SDK location.

Issue three: As in the Code editing window and at run time, Chinese display garbled

Solution: As the Code editing window garbled, only need to change the lower right corner of the IDE UTF-8 to GBK; runtime display garbled, 1, add compileoptions.encoding = "in Project->app->build.gradle GBK ". 2, can not be directly input in the layout file in Chinese, need to register in the R file, such as <activity android:label= "Chinese" > Changed to <activity android:label= "@string/chinese" Add <string name= "Chinese" > Chinese </string> in Strings.xml.

Issue four: As import engineering with JNI settings, compilation error

Workaround: General Eclipse Engineering, as can be imported directly. If there is a problem, confirm that the project is running well in Eclipse, export as engineering, and then import in as.

Question five: Invalid R-class path shown in Mainactivity.java

Workaround: As does not automatically generate R files for some reason. For example, if the project relies on a library file version that does not match the specified compilesdkversion, you need to manually specify the version number of the library file that needs to be compiled. For example, Android.compilesdkversion is 19, then add at the end of Project->app->build.gradle

dependencies {

Compile ' com.android.support:support-v4:+ ' changed to compile ' com.android.support:support-v4:19.+ '
Compile ' com.android.support:appcompat-v7:+ ' changed to compile ' com.android.support:appcompat-v7:19.+ '
}

Note dependencies{} and android{} siblings
