I am getting the following message in android LogCat

For downloading images in android emulator I have added internet permission in androidManifest.xml file, but looks like it is not working. I have also given 10MB space to android emulator as well.

any one guide me what could be the problem? thanks in advance.

Answer 1

I solved this problem adding permissions:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Answer 2

ImageLoader Constructor should be change to this.

public ImageLoader(Context context) {
    // Make the background thead low priority. This way it will not affect
    // the UI performance
    photoLoaderThread.setPriority(Thread.NORM_PRIORITY - 1);

    // Find the dir to save cached images
    if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
        cacheDir = new File(context.getCacheDir(), "LazyList");
    else
        cacheDir = context.getCacheDir();
    if (!cacheDir.exists())
        cacheDir.mkdirs();
}

By default it is like this

cacheDir = new File(android.os.Environment.getDataDirectory(), "LazyList");

You should change it to

cacheDir = new File(context.getCacheDir(), "LazyList");

I solved my problem 100% in android 2.1.
