无法运行Android的位图示例代码

Question

I am trying to run the sample from : http://developer.android.com/training/displaying-bitmaps/display-bitmap.html

However I encountered lots of errors like:

Description Resource Path Location Type

BuildConfig cannot be resolved to a variable    ImageGridFragment.java  /ImageGridActivity/src/com/example/android/bitmapfun/ui line 124    Java Problem

Description Resource Path Location Type

SuppressLint cannot be resolved to a type   Utils.java  /ImageGridActivity/src/com/example/android/bitmapfun/util   line 99 Java Problem

I ran thru Google but could get nothing. Adjusted the android build target to 4.0.3 (15) but still no clue. Anyone ran this sample successfully?

Thanks.

Answer 1

Here is my solution: 1.Create a new class:

package com.example.android.bitmapfun;

public class BuildConfig {
public static final boolean DEBUG = true;
}

2.Comment the lines that contain "SuppressLint":

//import android.annotation.SuppressLint;
//    @SuppressLint("NewApi")

Answer 2

Android developer tools r17 brings a feature to Eclipse where a class is auto built at build-time, called BuildConfig, which contains a constant that can be used by the app developer to sense whether the build is a dev build or a production build. This feature appears to be in the Eclipse integration support, so when using IntelliJ, this useful feature is not available

In gen folder with R.java there should be BuildConfig.java if your program compiled successfully.

/** Automatically generated file. DO NOT MODIFY */
package com.example.android.bitmapfun;

public final class BuildConfig {
    public final static boolean DEBUG = true;
}

Clean your project and try to launch it again.

It worked for me.

Answer 4

For me also it is not running directly import to eclipse. Just i put comments which lines is showing errors then it is working fine for me. May be it is not a right answer but we can see the application functionality by running the code so i did like that.
