Abstract

Claims (60)

1 . A method, comprising:

accessing an application package comprising executable application code and a machine-readable manifest;

extracting the machine-readable manifest from the application package;

decoding the machine-readable manifest into an intermediate manifest;

matching a portion of the intermediate manifest to an object signature;

inserting, in the intermediate manifest, instrument code relative to the object signature to produce an instrumented manifest;

encoding the instrumented manifest into an instrumented machine-readable manifest;

extracting the executable application code from the application package;

processing the executable application code to identify an instrumentation signature,

wherein processing the executable application code includes decompiling the executable application code into a generated source code file;

inserting instrumentation code relative to the instrumentation signature to produce instrumented executable application code; and

packaging the instrumented executable application code and the instrumented machine-readable manifest into an instrumented application package.

2 . The method of claim 1 , wherein the executable application code comprises binary Dalvik bytecode (DEX).

3 . The method of claim 1 , wherein the generated source code file comprises Smali text.

4 . The method of claim 1 , further comprising inserting the instrumentation code in at least one of directly before or directly after an instrumentation signature, respectively.

5 . The method of claim 1 , wherein the machine-readable manifest comprises Android layout view (AXML) content.

6 . The method of claim 1 , wherein at least one of the intermediate manifest and the instrumented manifest comprise extensible markup language (XML) instructions.

7 . The method of claim 1 , wherein packaging the instrumented executable application code into the instrumented application package further comprises:

receiving a package type; and

in response to the package type, packaging the instrumented executable application code into the instrumented application package having the package type.

8 . The method of claim 7 , wherein the package type is selected from a group comprising Android application bundle (AAB) or Android package kit (APK).

9 . The method of claim 1 , wherein extracting the executable application code from the application package further comprises extracting at least one of a resource or an asset from the application package.

10 . The method of claim 9 , wherein packaging the instrumented executable application code into the instrumented application package further comprises packaging the at least one of the resource or the asset in the instrumented application package.

11 . A method, comprising:

accessing an application package comprising executable manifest;

extracting the executable manifest from the application package;

decoding the executable manifest into an intermediate manifest;

matching a portion of the intermediate manifest to an object signature;

inserting, in the intermediate manifest, in at least one of before the object signature and after the object signature an instrumentation code to produce an instrumented manifest;

encoding the instrumented manifest into an instrumented machine-readable manifest;

extracting an executable application code from the application package;

decompiling the executable application code into a generated source code file; and

packaging the instrumented machine-readable manifest into an instrumented application package.

12 . The method of claim 11 , wherein the intermediate manifest comprises an Android manifest (AXML).

13 . The method of claim 11 , wherein the instrumented manifest comprises an extensible markup language (XML).

14 . The method of claim 11 , further comprising:

matching a portion of the generated source code file to an instrumentation signature;

inserting, in the generated source code file, in at least one of before the instrumentation signature and after the instrumentation signature, an instrumentation code to produce an instrumented source code;

compiling the instrumented source code into an instrumented executable application code; and

packaging the instrumented executable application code into the instrumented application package.

15 . The method of claim 14 , wherein the executable application code comprises binary Dalvik bytecode (DEX).

16 . The method of claim 14 , wherein packaging the instrumented executable application code into the instrumented application package further comprises:

receiving a package type; and

in response to the package type, packaging the instrumented executable application code into the instrumented application package having the package type.

17 . The method of claim 16 , wherein the package type is selected from a group comprising Android application bundle (AAB) or Android package kit (APK).

18 . The method of claim 11 , wherein the generated source code file comprises Smali text.

19 . A system, comprising:

a data storage maintaining an application package comprising an executable manifest;

a processor coupled to a computer memory and having stored thereon instructions to cause the processor to:

access the application package from the data storage;

extract the executable manifest from the application package;

decode the executable manifest into an intermediate manifest;

match a portion of the intermediate manifest to an object signature;

insert, in the intermediate manifest in at least one of before the object signature and after the object signature, an instrumentation code to produce an instrumented manifest;

encode the instrumented manifest into an instrumented machine-readable manifest;

extract an executable application code from the application package;

decompile the executable application code into a generated source code file;

package the instrumented machine-readable manifest into an instrumented application package; and

store the instrumented application package in the data storage.

20 . The system of claim 19 , wherein the intermediate manifest comprises an Android manifest (AXML) and the instrumented manifest comprises an extensible markup language (XML).
