If we unzip the sample and explore the AndroidManifest.xml, we see that the entry point com.sdktools.android.MainActivity is not found in the code of the sample. This an indication of a packed sample. You can identify the packing technique using droidlysis or APKiD. If we use droidlysis, We can see the it the sample uses DexClassLoader, malware uses JsonPacker packer. So we need to get the decrypted payload of the sample.
