Android示例-加速度计和APIDemos无法构建

Question

I am new to Android development. I have succesfully installed eclipse with Android Developer Tool plugin and many of the samples work fine.

But Android samples - Accelerometer and APIDemos do not build . I see many build errors notifying to fix the errors in code. I dont think Google has released APIDemo sample with build errors.

Thanks in advance, please advice how to fix these errors, or if any configuration/setting is required.

I have set the Java compiler compliance level to 1.6.

Error information(for acceralometer sample):

The project contains error(s) in application. Please fix them before running

Error details:

    The method onAccuracyChanged(Sensor, int) of type AccelerometerPlayActivity.SimulationView must override a superclass method    
    AccelerometerPlayActivity.java  /AccelerometerPlay/src/com/example/android/accelerometerplay    line 456    
    Java Problem
    Call requires API level 8 (current min is 5): 
    android.view.Display#getRotation    AccelerometerPlayActivity.java  /AccelerometerPlay/src/com/example/android/accelerometerplay    
    line 389    Android Lint Problem

Answer 1

Look for the line androidminSdkVersion ="5" in your android.manifest file

and change its value from 5 to 8 or anything more than 8

Alternative is Go to project properties by right clicking on you project, thereafter look for Android in properties. You have to select the build target here equivalent to the api for which it the sample project is build for

Refer Image

Say if you are using the sample from folder android-12 then you have to check the same option(ie API Level 12 ) here in properties

Answer 2

A possible reason can be a slow PC, which does not build in time. Then errors occur due to absence of R.java

In that case (errors are with something like R.id.stuff ), build the project and wait.

Answer 3

I found the fix myself!

Earlier I tried with Andriod version 4.0. Now I just tried ApiDemos sample with Android version 4.1.2. It worked fine. I also deployed the apk in my mobile. It just works fine.
