JQuery Cannot Load Audio File

October 23, 2015 by blogmeister·0 Comments

This was a problem that got me stuck for a day. JQuery just cannot seem to load an audio file because the return type is always a string.

The solution that I came up with was to use traditional Javascript code using XMLHttpRequest.

var xhr = new XMLHttpRequest();
xhr.addEventListener('progress', function(e) {
    if (e.lengthComputable) {
        var percentComplete = e.loaded / e.total;
        console.log('Status: Downloading: ' + percentComplete + '%');
    }
});
xhr.addEventListener('load', function(blob) {
    if (xhr.status == 200) {
        audio.src = window.URL.createObjectURL(xhr.response);
    }
});
xhr.open('GET', src);
xhr.responseType = 'blob';
xhr.send(null);

var xhr = new XMLHttpRequest();

xhr.addEventListener('progress', function(e) {

if (e.lengthComputable) {

var percentComplete = e.loaded / e.total;

console.log('Status: Downloading: ' + percentComplete + '%');

}

});

xhr.addEventListener('load', function(blob) {

if (xhr.status == 200) {

audio.src = window.URL.createObjectURL(xhr.response);

}

});

xhr.open('GET', src);

xhr.responseType = 'blob';

xhr.send(null);

There could be JQuery plugins that can do this but I was not able to find any. Traditional XMLHttpRequest can still do a lot of wonders ;).

How To Trace Obfuscated Code With Stacktrace In Android

October 17, 2015 by blogmeister·0 Comments

There came a time that I received some stack trace exception logs which showed obfuscated classes from my Android app.

Now, the problem is how do I know which obfuscated class is linked to my original classes.

The answer lies in the mapping.txt file that is generated by ProGuard. This can be found in your project main’s build/outputs/mapping/[…flavor_if_any…]/mapping.txt folder.

There is also a tool that can give you a better visual result compared to manually looking at the mapping.txt file and your stack trace file which can be a hassle especially if you have only 1 monitor screen as it is cumbersome to keep on alt-tabbing just to pinpoint the class you are looking for.

The command is

[android-sdk]/tools/proguard/bin/retrace.bat -verbose [path_of_mapping.txt] [path_of_stack_trace_file]

1	[android-sdk]/tools/proguard/bin/retrace.bat -verbose [path_of_mapping.txt] [path_of_stack_trace_file]
