Install the RE manager.3. Use the RE manager to modify the "Platform.xml" file in the "/system/etc/permissions

There are two ways to resolve this:1.by modifyingAndroidSystem of source code, openSDThe card read and Write permission, the detailed modification method and the explanation, may refer to the online materialhttp://www.ifeegoo.com/ Android-debug-static-storage-paths-are-not-available-from-aid-system-error-analysis-and-solution.html2.in the application, theandroid:shareduserid= "Android.uid.system"insteadandr

This article for everyone in detail under the Android Read assets picture resources to save the specific implementation of SD card, interested members can refer to Ha, I hope to help you have copy code code as follows: public class Readbitmap { public void ReadByte (context C, String name, int indexint) { byte[] b = null; int[] Intarrat = C.getresources ().

Private Bitmap Getdiskbitmap (String pathstring) {NBSP;NBSP; bitmapbitmap=null ;NBSP;NBSP; try NBSP;NBSP; NBSP;NBSP;NBSP;NBSP;{NBSP;NBSP; filefile=new file (pathstring); if (file.exists ()) { Bitmap = Bitmapfactory.decodefile (pathstring); NBSP;NBSP;NBSP;NBSP;NBSP;NBSP;NBSP;NBSP;}NBSP;NBSP; }catch (exceptione) NBSP;NBSP;NBSP;NBSP;{NBSP;NBSP; //todo:handleexception NBSP;NBSP; } r

This article describes the Android programming method for reading local SD card images. Share to everyone for your reference, specific as follows: Private Bitmap Getdiskbitmap (String pathstring) { Bitmap Bitmap = null; Try { File File = new file (pathstring); if (file.exists ()) { bitmap = Bitmapfactory.decodefile (pathstring); } catch (Exception e) { //Todo:handle

installed at an offset, the SD card may become unavailable.3) In addition, if the SD card is unavailable, we can pull out the SD card to see if there is dust on the chip. If yes, clear the SD
