Android进入设置中应用对应的详情界面

有时候为了引导用户操作，例如手动赋予权限等，需要拉起应用对应的详情界面。

此时，可以使用Settings中定义的ACTION_APPLICATION_DETAILS_SETTINGS。

源码中的描述如下：

..............
/**
* Activity Action: Show screen of details about a particular application.
* <p>
* In some cases, a matching Activity may not exist, so ensure you
* safeguard against this.
* <p>
* Input: The Intent's data URI specifies the application package name
* to be shown, with the "package" scheme.  That is "package:com.my.app".
* <p>
* Output: Nothing.
*/
@SdkConstant(SdkConstantType.ACTIVITY_INTENT_ACTION)
public static final String ACTION_APPLICATION_DETAILS_SETTINGS =
"android.settings.APPLICATION_DETAILS_SETTINGS";
................

具体使用时的代码类似于：

............
public static final String SETTINGS_ACTION =
"android.settings.APPLICATION_DETAILS_SETTINGS";
..............
mSetPermissionView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent()
.setAction(SETTINGS_ACTION)
.setData(Uri.fromParts("package",
getActivity().getPackageName(), null));
startActivity(intent);
}
});
................

Intent携带数据格式为pacakge:包名，类似于：

package:stark.a.is.zhang.transfer
