I read all previous threads related to this matter but I could not solve my problem. Hence I post it here. My application has a text to pdf converter and I used iText for it. When I tried to install the application to the device the console says,
Installation error: INSTALL_PARSE_FAILED_NO_CERTIFICATES.
Please check logcat output for more details.
Launch canceled!
In logcat it says, 01-15 14:30:09.019: E/PackageParser(2454): Package com.example.example has no certificates at entry res/layout/activity_main.xml; ignoring!
I'm using JDK 1.6 and android Android 4.4. I uninstalled previous .apk and clean and build the project.
EDIT: As a solution for this problem, I tried to sing the application using eclipse. But after gave the keystore and alias it is gave error as "duplicate files at the same path inside the apk". I checked my lib folder if there is any duplicate jars and cleaned and rebuilt it. But still I cannot export signed apk.
As far as I can understand issues for above both cases that jars may be has file same as in my application. But I don't know hot to solve this. Any suggestion would be welcome to get rid of this problem.
