Why signed android apk is not running on emulator

Question

I have made a signed apk of an android project. Whenever my client try to run it on the emulator, he faces the following error message:

D:\Android\android-sdk-
windows\tools>adb install -r abc.apk
500 KB/s (6940708 bytes in 13.534s)
        pkg: /data/local/tmp/abc.apk
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]

What is the resolution?

Is an unsigned version of your app already installed on the emulator? — Janusz, Mar 31 '10 at 08:01
I know you say it's signed, but that error msg sounds like to me it's not. — SteelBytes, Mar 31 '10 at 09:52

In my case it was because I signed it on a machine running JDK 7. Downgrading to JDK 6 fixed the problem. Thanks java.lang.SecurityException when install apk for the suggestion!

If you're signing yourself with jarsigner and have JDK 7 you can add the options "-digestalg SHA1 -sigalg MD5withRSA" to the jarsigner command and it will work with JDK7. – gravitron Feb 04 '12 at 15:12
How @GregEnnis . can you please elaborate ? – AbdulSaleem Aug 01 '17 at 12:17
@AbdulSaleem not really, that answer was 5 years ago. I urge you to switch to Android Studio at this point – Greg Ennis Aug 03 '17 at 20:52

As mentioned by steelbytes, the error INSTALL_PARSE_FAILED_NO_CERTIFICATES suggests that the APK isn't signed like you think it is.

Run this command to verify which certificate was used to sign the APK:
jarsigner -verify -verbose -certs abc.apk

For each entry in the APK, you should see something like this:

sm    152412 Wed Oct 14 14:16:52 CEST 2009 classes.dex

      X.509, CN=Meebo, OU=Meebo, O=Meebo, L=Mountain View, ST=California, C=US
      [certificate is valid from 28/10/08 06:49 to 13/08/82 07:49]

Otherwise, if the APK isn't signed, you'll get the message jar is unsigned.

try below code it's worked for me.

Below line run when your jdk version is 6 for singing the apk

H:\Keytool>"C:\Program Files\Java\jdk1.6.0_09\bin\jarsigner.exe" -verbose -keystore donate.keystore "H:\Keytool\yourapkName.apk.apk" donate.keystore 

Below line run when your jdk version is 7 for singing the apk

H:\Keytool>"C:\Program Files\Java\jdk1.7.0_21\bin\jarsigner.exe" -verbose -keyst
ore denote.keyStore "H:\Keytool\yourapkName.apk" denote.keyStore -digestalg SHA1 -sigalg MD5withRSA

"-digestalg SHA1 -sigalg MD5withRSA" solved it for me – FooBarTheLittle Oct 30 '14 at 13:45 — FooBarTheLittle, Oct 30 '14 at 13:45

As Dan pointed out, check if you're running JDK 7. More info: http://code.google.com/p/android/issues/detail?id=19567

You can run the Command:

C:\Program Files\Android\android-sdk\platform-tools>adb logcat

It will give you a more detail on which exact file is not signed:

Package has no certificates at entry assets/META-INF/AIR/application.xml; ignoring!

You could check if the client has not disabled installation of unsigned apps in the emulator.

All apps must be signed; an Android device (or emulator) will not accept an unsigned APK for installation. – Christopher Orr Apr 01 '10 at 17:39
If you're referring to allowing non-Market apps, this setting doesn't apply when "sideloading" via `adb`. – Christopher Orr Apr 01 '10 at 17:40
No I am specifically referring to allowing unsigned application to be allowed to be installed. – the100rabh Apr 02 '10 at 05:33
Ok, I haven't seen this setting before. I tried uploading an unsigned APK to a device and to an emultor and both refused it with `INSTALL_PARSE_FAILED_NO_CERTIFICATES`. Where would this be configured? – Christopher Orr Apr 02 '10 at 10:06
The setting I am talking of is at Settings->Applications->Unknown Sources – the100rabh Apr 02 '10 at 19:21

That's the setting I referred to in my second comment (it allows non-Market apps, not unsigned apps). Try it for yourself; loading an unsigned APK onto either a device or emulator with "Unknown Sources" enabled *still* results in the device rejecting the APK. The PackageParser will say "Package com.example has no certificates at entry AndroidManifest.xml; ignoring!". – Christopher Orr Apr 04 '10 at 13:30
