can i access dumpsys file from android -


i developing tracker application need know application starting hardware (by using pid) e.g camera or gps. information logged dumpsys file in android. want access file in application ,do analysis on , extract required information. can access file through adb when same commands run form java coding permission denied error occurs. have added android.permission.dump in manifest file still error.

unfortunately "android.permission.dump" granted system apps.

unless sign application system signature , use system shared user id (android:shareduserid="android.uid.system") in manifest, won't able permission.

what redirect dumpsys output manually external storage , examine file fileinputstream , bufferedreader

ex: dumpsys > /sdcard/my_dump.txt

in .java class:

fileinputstream fis     = new fileinputstream("/sdcard/my_dump.txt"); bufferedreader  bfr     = new bufferedreader (new inputstreamreader(fis)); stringbuilder   builder = new stringbuilder  (); string          line    = "";  while ((line = br.readline()) != null) {     builder.append(line);     log.i("test", line); }

you can check builder 

string whateveryouarelookingfor = "camera"; if (builder.tostring().contains(whateveryouarelookingfor)) {     //do }

i know it's not best solution can still out of it.

hope find solution, cheers.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
