Android权限判断checkPermission

判断本程序是否拥有某权限的方法：

1. private static final String EXTERNAL_STORAGE_PERMISSION = "android.permission.WRITE_EXTERNAL_STORAGE";
2. private static boolean hasExternalStoragePermission(Context context) {
3. int perm = context.checkCallingOrSelfPermission(EXTERNAL_STORAGE_PERMISSION);
4. return perm == PackageManager.PERMISSION_GRANTED;
5. }

private static final String EXTERNAL_STORAGE_PERMISSION = "android.permission.WRITE_EXTERNAL_STORAGE";
 
private static boolean hasExternalStoragePermission(Context context) {
		int perm = context.checkCallingOrSelfPermission(EXTERNAL_STORAGE_PERMISSION);
		return perm == PackageManager.PERMISSION_GRANTED;
	}

判断某个程序是否拥有某权限的方法：

1. private static boolean checkPermission(Context context, String permName, String pkgName){
2. PackageManager pm = context.getPackageManager();
3. if(PackageManager.PERMISSION_GRANTED == pm.checkPermission(permName, pkgName)){
4. System.out.println(pkgName + "has permission : " + permName);
5. return true;
6. }else{
7. //PackageManager.PERMISSION_DENIED == pm.checkPermission(permName, pkgName)
8. System.out.println(pkgName + "not has permission : " + permName);
9. return false;
10. }
11. }

private static boolean checkPermission(Context context, String permName, String pkgName){
		PackageManager pm = context.getPackageManager();
		if(PackageManager.PERMISSION_GRANTED == pm.checkPermission(permName, pkgName)){
			System.out.println(pkgName + "has permission : " + permName);
			return true;
		}else{
			//PackageManager.PERMISSION_DENIED == pm.checkPermission(permName, pkgName)
			System.out.println(pkgName + "not has permission : " + permName);
			return false;
		}
	}
