I would recommend using SharedPreferences<\/a> to achieve this. They are meant to be to retain app state when run at a later time. <\/p>\n

In your case, you need to use putBoolean()<\/code> method from SharedPreferences.Editor<\/a> something like this:<\/p>\n

“Start” button onClickListener:<\/strong> <\/p>\n

SharedPreferences sharedPref = context.getSharedPreferences(context, MODE_PRIVATE);\nSharedPreferences.Editor editor = sharedPref.editor();\neditor.putBoolean(\"isJobRunning\",\"true\");\neditor.commit();\n<\/code><\/pre>\n
In the same way, you set the isJobRunning<\/code> to false once “End” button is called.<\/p>\n
I would also move this code to a dedicated method something like this:<\/p>\n
private void updateJobStatus(boolean isJobRunning) {\n    SharedPreferences sharedPref = context.getSharedPreferences(context, MODE_PRIVATE);\n    SharedPreferences.Editor editor = sharedPref.editor();\n    editor.putBoolean(\"isJobRunning\", isJobRunning); \/\/ difference is visible here! \n    editor.commit();\n}\n<\/code><\/pre>\n
On the onCreateView() method on the Activity, you can check if the job is running this way:<\/p>\n
SharedPreferences sharedPref = context.getSharedPreferences(context, MODE_PRIVATE);\nsharedPref.getBoolean(\"isJobRunning\", false); \/\/ Here, `false` is the default value if the key is not located in `SharedPref`\n<\/code><\/pre>\n<\/p><\/div>\n
<\/div>\n<\/div>\n
            <\/span> <\/p><\/div>\n<\/div>\n
