There is an android app that does something and print logs to display.
I need to change it by adding log to file function.
app.apk => dex2jar => app.jar
app.jar => javadec => readable java code.
I found function, that prints logs to display:
where is obj is string to print
there is a function to write a file
Ok, in java it should be easy:
writeDateFile("logDir/log.txt", obj.getBytes(), 0);
But how to paste it into smali file?

Code:
private void T10ShowResult(final int[] array, final boolean b) {
String obj = "";
[S]bla bla bla
and[/S]
[COLOR="#FF0000"]this.SendMessage(obj, array, -1, 1, GetResultService.stateFlag);[/COLOR]
}where is obj is string to print
there is a function to write a file
Code:
public void writeDateFile(final String s, final byte[] b, final int n) throws Exception {
final FileOutputStream openFileOutput = this.context.openFileOutput(new String(s.getBytes("iso8859-1"), "utf-8"), n);
if (b != null && b.length > 0) {
openFileOutput.write(b);
}
openFileOutput.close();
}writeDateFile("logDir/log.txt", obj.getBytes(), 0);
