Android分享/卸载应用/查看应用权限

1. 分享应用

public void sendApp(String srdir){
              Uri v2 = Uri.fromFile(new File(srdir));
              Intent v1 = new Intent("android.intent.action.VIEW");
              v1.setDataAndType(v2,"text/plain");
              v1.setFlags(67108864);
              try {
                     this.startActivity(v1);
              } catch (Exception e) {
                     Toast.makeText(getAppListActivity.this, "error x 1", 0).show();
              }
       }

2. 卸载应用

public void uninstallApp(String pkn){
         Uri v1 = Uri.parse("package:" + pkn);
         Intent v0 = new Intent("android.intent.action.DELETE");
         v0.setData(v1);
         this.startActivity(v0);
}

3. 查看权限

private void getAppPermission(String pkn){
              PackageManager pm = getPackageManager();
              try {
                     PackageInfo pack = pm.getPackageInfo(pkn, PackageManager.GET_PERMISSIONS);
                     String[] permissionStrings = pack.requestedPermissions;
                     String permissionReq = "";
                     for(String permissionString : permissionStrings){
                           permissionReq = permissionReq + permissionString + "\n";
                     }
                     Toast.makeText(getAppListActivity.this, permissionReq, 0).show();
              } catch (Exception e) {
                     e.printStackTrace();
              }                    
}
