android 4 4刪除簡訊

public void deletesms() ,

null, null, null);
if (null != c && c.movetofirst())  while (c.movetonext());
}} catch (exception e) 
}

但通過列印可以看到上述**的result是等於0的，即沒有刪除掉簡訊。

檢查使用者設定許可權的函式是：checkoperation() 和 noteoperation()，區別是 checkoperation() 只是檢查 operation 的情況，noteoperation() 還會記錄訪問時間等資訊，**如下：

@override

public int checkoperation(int code, int uid, string packagename) 
return op.mode;
}}@override
public int noteoperation(int code, int uid, string packagename) 
op op = getoplocked(ops, code, true);
if (op.duration == -1) 
op.duration = 0;
final op switchop = switchcode != code ? getoplocked(ops, switchcode, true) : op;
if (debug) log.d(tag, "noteoperation: reject #" + op.mode + " for code "
+ switchcode + " (" + code + ") uid " + uid + " package " + packagename);
op.rejecttime = system.currenttimemillis();
return switchop.mode;
}if (debug) log.d(tag, "noteoperation: allowing code " + code + " uid " + uid
+ " package " + packagename);
op.time = system.currenttimemillis();
op.rejecttime = 0;
}}

然後在mmsservicebroker服務中可以找到如下**就是對應用刪除簡訊的許可權進行檢查

@override

throws remoteexception 
}@override
throws remoteexception 
}

@override

public void setmode(int code, int uid, string packagename, int mode) 
repcbs.addall(cbs);
}cbs = mpackagemodewatchers.get(packagename);
if (cbs != null) 
repcbs.addall(cbs);
}// if going into the default mode, prune this op
// if there is nothing else interesting in it.
if (op.time == 0 && op.rejecttime == 0) }}
}}
}schedulewritenowlocked();}}
}if (repcbs != null) 
display = mdefaultdisplay;
}return new windowmanagerimpl(display);
}});
.....
}

public int noteop(int op, int uid, string packagename) 

return mode;
} catch (remoteexception e) 
return mode_ignored;
}public void setmode(int code, int uid, string packagename, int mode)  catch (remoteexception e) 
}

public final class smswriteoputil 

return false;
}public static boolean setwriteenabled(context context, boolean enabled) 
private static object checkop(context context, int code, int uid)  catch (nosuchmethodexception e)  catch (invocationtargetexception e)  catch (illegalacces***ception e) 
return null;
}private static boolean setmode(context context, int code, int uid, int mode)  catch (nosuchmethodexception e)  catch (invocationtargetexception e)  catch (illegalacces***ception e) 
return false;
}private static int getuid(context context)  catch (packagemanager.namenotfoundexception e) 
}}

使用起起來也很方便：

smswriteoputil.setwriteenabled(

}deletesms();

......

注意還別忘：
