I simply wrote a program today and found that it could not run all the time, prompting that the installation failed on the physical device
INSTALL_PARSE_FAILED_MANIFEST_MALFORMED Installation failed due to: ‘null’
After checking on the Internet, most of the brothers said that it was a problem with the test mark, so just add it
android:testOnly="false"But there are still problems after trying
Another brother said that this problem is related to the manifest file. It may be that there is a problem with the configuration of the manifest file. Therefore, I checked it from here. However, I was also very curious about how a hello world program has a configuration problem. I didn’t see any exceptions in the xml. I went to the apk generation directory to directly try to install it:
adb install -r -d a.apkhere I saw the error messages:
adb: failed to install app-debug.apk: Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackageLI: /data/app/vmdl631790294.tmp/base.apk (at Binary XML file line #20): com.leonard.goot.MainActivity: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present]
Find the problem, because the activity does not have the export property caused by the modification can be installed after debugging, Done!
