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?

Answer 1

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!

Answer 2

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 .

Answer 3

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

Answer 4

正如Dan指出的，检查您是否正在运行JDK 7.更多信息： http ： //code.google.com/p/android/issues/detail？id = 19567

Answer 5

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! 

Answer 6

您可以检查客户端是否未在模拟器中禁用未签名应用程序的安装。
