我把表中的error_context提出来!

1."FATAL EXCEPTION: main java.lang.SecurityException: Permission Denial: starting Intent { cmp=com.funo.activity/.DemoActivity } from ProcessRecord{450046c0 1063:com.funo.activity/10044} (pid=1063, uid=10044) requires android.permission.ACCESS_CHECKIN_PROPERTIES at android.os.Parcel.readException(Parcel.java:1247) at android.os.Parcel.readException(Parcel.java:1235) at android.app.ActivityManagerProxy.startActivity(ActivityManagerNative.java:1298) at android.app.Instrumentation.execStartActivity(Instrumentation.java:1373) at android.app.Activity.startActivityForResult(Activity.java:2817) at android.app.Activity.startActivity(Activity.java:2923) at com.funo.activity.ClientLogRecordActivity$2.onClick(ClientLogRecordActivity.java:45) at android.view.View.performClick(View.java:2408) at android.view.View$PerformClick.run(View.java:8816) at android.os.Handler.handleCallback(Handler.java:587) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4627) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) at dalvik.system.NativeStart.main(Native Method) "

2.。。。
