我正在使用以下代码在Android中拨打电话,但它给了我安全例外,请帮助。

 posted_by = "111-333-222-4";

 String uri = "tel:" + posted_by.trim() ;
 Intent intent = new Intent(Intent.ACTION_CALL);
 intent.setData(Uri.parse(uri));
 startActivity(intent);

权限

 <uses-permission android:name="android.permission.CALL_PHONE" />

异常

为了避免这种情况,可以使用GUI来输入权限。Eclipse会考虑在哪里插入权限标记,通常情况下不这样做是正确的

其他回答

对于使用intent进行调用活动,您应该请求适当的权限。

为此,在AndroidManifest.xml文件中包含使用权限。

<uses-permission android:name="android.permission.CALL_PHONE" />

然后在您的活动中包含以下代码

if (ActivityCompat.checkSelfPermission(mActivity,
        Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
    //Creating intents for making a call
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:123456789"));
    mActivity.startActivity(callIntent);

}else{
    Toast.makeText(mActivity, "You don't assign permission.", Toast.LENGTH_SHORT).show();
}

从拨号器调用(不需要权限):

   fun callFromDailer(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_DIAL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

从应用程序直接呼叫(需要权限):

  fun callDirect(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_CALL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: SecurityException) {
            Toast.makeText(mContext, "Need call permission", Toast.LENGTH_LONG).show()
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

许可:

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

在Android中,对于某些功能,您需要将权限添加到Manifest文件。

转到项目AndroidManifest.xml 单击Permissions选项卡 点击添加 选择使用权限 请看下面的快照

6.保存清单文件,然后运行项目。 您的项目现在应该按预期运行。

// Java
String mobileNumber = "99XXXXXXXX";
Intent intent = new Intent();
intent.setAction(Intent.ACTION_DIAL); // Action for what intent called for
intent.setData(Uri.parse("tel: " + mobileNumber)); // Data with intent respective action on intent
startActivity(intent);

// Kotlin
val mobileNumber = "99XXXXXXXX"
val intent = Intent()
intent.action = Intent.ACTION_DIAL // Action for what intent called for
intent.data = Uri.parse("tel: $mobileNumber") // Data with intent respective action on intent
startActivity(intent)

你可以使用Intent。ACTION_DIAL代替Intent.ACTION_CALL。这将显示已输入号码的拨号器,但允许用户决定是否实际拨打电话。ACTION_DIAL不需要CALL_PHONE权限。
