Exception 'open failed: EACCES (Permission denied)' on Android

Answer


Answer




I am getting




open failed: EACCES (Permission denied)





on the line OutputStream myOutput = new FileOutputStream(outFileName);



I checked the root, and I tried android.permission.WRITE_EXTERNAL_STORAGE.



How can I fix this problem?



try {
    InputStream myInput;

    myInput = getAssets().open("XXX.db");


    // Path to the just created empty db
    String outFileName = "/data/data/XX/databases/"
            + "XXX.db";

    // Open the empty db as the output stream
    OutputStream myOutput = new FileOutputStream(outFileName);

    // Transfer bytes from the inputfile to the outputfile
    byte[] buffer = new byte[1024];

    int length;
    while ((length = myInput.read(buffer)) > 0) {
        myOutput.write(buffer, 0, length);
    }

    // Close the streams
    myOutput.flush();
    myOutput.close();
    myInput.close();
    buffer = null;

    outFileName = null;
}
catch (IOException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}

Answer



I had the same problem... The was in the wrong place. This is right:




 
        
        ...
        
            ...
             
                ...



The uses-permission tag needs to be outside the application tag.
