Answer 1

Please specify how are you generating the apk file becausw to generate the apk file we need to generate it using certifiate it may be debug certificate or the release certificate if the generated apk dont have any of them will through the error so generate the apk using eclipse it will automatically generate the apk file using debug certificate.

Answer 2

you should sign to apk before install.

1)keytool -genkey -keystore (name).keystore -validity 10000 -alias (name)

2)answer some question (ex:name, company...

3)after make keystore file,you combine apk and ketstore

if these file are located same directory

jarsigner -keystore （name）.keystore -verbose LunarLander.apk （name）

apk size increase 2kb+;

after this install apk to avd
