无法在android中授予我的自定义内容提供商权限? [英] Not able to grant my custom content provider permission in android?
问题描述
我正在开发内容提供商应用程序.
在该应用程序的清单中，我在application标记中放置了一个provider元素.
以下是代码
I was developing a content provider app.
In the manifest of that app I was placed a provider element In the application tag.
The following are the code
<provider
android:name=".PlatesContentProvider"
android:authorities="com.tag.custom_contentproviderdemo.Plates"
android:enabled="true"
android:readPermission="PlatesContentProvider._READ_PERMISSION"
android:writePermission="PlatesContentProvider._WRITE_PERMISSION"
android:exported="true" >
我还开发了另一个应用程序CPClient.它将向上述内容提供商读取/写入数据.
我在清单文件中被声明为元素.
I also developed another app namely CPClient. It will read/write data to the content provider mentioned above.
I was declared element in its manifest file.
以下是代码
<uses-permission android:name="PlatesContentProvider._READ_PERMISSION"/>
<uses-permission android:name="PlatesContentProvider._WRITE_PERMISSION"/>
在CPClient的启动器活动中，我已获得此权限.如果未授予该权限，则我将请求权限.
但是在请求权限时，它不会显示请求权限"对话框，并且始终不会授予权限.
In the launcher activity of the CPClient I was checked for this permission .If it is not granted means I will request for permission.
But in requesting permission it does not shown request permission dialog and always permission is not granted.
以下是代码
private final String permissionsRequired="PlatesContentProvider._READ_PERMISSION";
private final String permissionsRequired2= "PlatesContentProvider._WRITE_PERMISSION";
private String[] permissions=new String[]{permissionsRequired,permissionsRequired2};
public void process()
{
checkPermission();
if(!permission_granted)
{
Toast.makeText(this,"Permission not granted.Requesing permission....",Toast.LENGTH_SHORT).show();
requestPermission1();return;
}
else
{
bindWidgetEvents(); //After permission granted I will perform some process
Log.d(TAG,"Permission granted");return;
}
}
public void checkPermission()
{
int permit=this.checkSelfPermission(permissionsRequired);
if(permit== PackageManager.PERMISSION_GRANTED) {
Log.d(TAG, "permission granted");
permission_granted=true;return;
}
else
Log.d(TAG,"permission not granted");
permission_granted=false;
}
public void requestPermission1()
{
//boolean show=this.shouldShowRequestPermissionRationale(permissionsRequired);
//Log.d(TAG,"need to show = "+show);
Thread thread=new Thread()
{
public void run()
{
Log.d(TAG,"B4 call request permission");
requestPermissions(permissions,CONTENT_PROVIDER_PERMISSION_REQUEST_CODE);
Log.d(TAG,"after call request permission");
}
};
thread.start();
}
public void onRequestPermissionsResult(int requestCode,String permissions1[], int[] grantResults)
{
Log.d(TAG,"onRequestPermissionsResult. req code="+requestCode);
if(requestCode==CONTENT_PROVIDER_PERMISSION_REQUEST_CODE)
{
Log.d(TAG,"Content provider permsion request code");
if(grantResults==null)
{
Log.d(TAG,"grant results is null");
Toast.makeText(this,"UnKnown error happened",Toast.LENGTH_LONG).show();
return;
}
int grant_results_size=grantResults.length;
Log.d(TAG,"Grant result size="+grant_results_size);
if(grant_results_size<1)
{
Log.d(TAG,"grant results size is <1");
Toast.makeText(this,"UnKnown error happened",Toast.LENGTH_LONG).show();
return;
}
if(grantResults[0]!=PackageManager.PERMISSION_GRANTED)
{
Log.d(TAG,"Permission not granted");
Toast.makeText(this,"Read Permission not granted",Toast.LENGTH_LONG).show();
}
if(grantResults[1]!=PackageManager.PERMISSION_GRANTED)
{
Log.d(TAG,"Permission not granted");
Toast.makeText(this,"Write Permission not granted",Toast.LENGTH_LONG).show();return;
}
Log.d(TAG,"Permission granted");
Toast.makeText(this,"Permission granted",Toast.LENGTH_SHORT).show();
bindWidgetEvents();
return;
}
else
{
Log.d(TAG,"not a Content provider permsion request code");
}
}
以下是android sdk的详细信息
我的目标和最低SDK版本在内容提供商应用程序和CPClient中均为23.
我不知道哪里出问题了?
欢迎大家提出自己的想法.
The following are the android sdk details
my target and min sdk version is 23 in the both content provider app and my CPClient.
I don't know where I will go wrong?
All are welcome to give their ideas.
推荐答案
您应该在清单"块以及提供者中声明您的权限.
You should declare your permissions in 'manifest' block as well as in provider.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="your.package">
<permission
android:name="PlatesContentProvider._READ_PERMISSION"
android:protectionLevel="normal" />
<permission
android:name="PlatesContentProvider._WRITE_PERMISSION"
android:protectionLevel="normal" />
<application>
<provider
android:name=".PlatesContentProvider"
android:authorities="com.tag.custom_contentproviderdemo.Plates"
android:enabled="true"
android:readPermission="PlatesContentProvider._READ_PERMISSION"
android:writePermission="PlatesContentProvider._WRITE_PERMISSION"
android:exported="true" >
</application>
</manifest>
