PackageManager.PackageManager.GetApkFileEntry fail on resolve debugged apk's

[burak1000]

I try many time for PackageManager.Exist("mypackage"). Exit method crash.
because it use PackageManager.GetApkFileEntry. but GetApkPath more stable and find my apk's path.

I think. PackageManager.Exist method edit like as following

public bool Exists ( String package ) {
try {
return GetApkPath ( package ) != null;
} catch ( FileNotFoundException) {
return false;
}
}

What are you passing as the package value? Because the GetApkFileEntry calls GetApkPath

return FileEntry.Find ( this.Device, GetApkPath ( package ) );

The package is not the path to your apk, it is your package name. From that value, the system calls pm path <package_name> and gets where the package lives on the device.

Please explain the scenario that it fails so I can attempt to reproduce it.

if i try like this:

string package_path = "";    
try 
{     
package_path = tmpdevice.PackageManager.GetApkPath("com.LedFire.Cathay"); 
}     
catch (Exception apk_not_found_exception) { }
if (package_path == "") 
{ 
Console.WriteLine("LedFire not loaded on this machine: " + tmpdevice.SerialNumber); continue; 
}

and works good.

after this code package_path set to "/data/app/com.LedFire.Cathay-25.apk"

but i try like this Exist() method always returned false.

Boolean LedFire_exist = tmpdevice.PackageManager.Exists("com.LedFire.Cathay");
if (!LedFire_exist)  Console.WriteLine("LedFire not loaded on this machine: " + tmpdevice.SerialNumber); continue; 

and not working.

my package name is "com.LedFire.Cathay" . but i think ,because of "-25 ".
LedFire is my app and under development and reinstall offen.
